Minicourse on open quantum systems: fundamentals, collisional models, and path integrals
July 1 – 5, 2024
São Paulo, Brazil
Venue: Principia Institute
Home
This one-week course is designed to provide master’s students in physics with an introduction to advanced methods for tackling the dynamics of quantum many-body experiments.
The initial focus of the course will delve into the language of open quantum systems, which serves as the foundational framework for experiments involving ultracold atoms or molecules, as well as modern many-body quantum optics. Specifically, lectures will elucidate notable distinctions from the unitary description of quantum mechanics, employing Lindblad master equations and collisional models. To reinforce understanding, tutorial sessions will be conducted to ensure a robust common foundation among participants.
In the latter part of the course, attention will shift towards demonstrating how non-equilibrium quantum field theory methods, initially formulated within the realm of high-energy physics, offer invaluable insights for deciphering the dynamics of contemporary quantum experimental setups. Students will gain insight into the technical and conceptual challenges inherent in these experiments, while exploring how a non-unitary path integral description of their dynamics can unlock regimes beyond the reach of conventional numerical or analytical approaches.
The course will also offer a glimpse into the frontiers of a specific class of experiments: the realm of strongly correlated dynamics in driven-open systems of many-body cavity quantum electrodynamics.
Pre-requisites: A postgraduate course on quantum mechanics.
There is no registration fee and limited funds are available for travel and local expenses.

Cosmological History: from Gravitational Waves to Exoplanets
July 29 – August 9, 2024
São Paulo, Brazil
ICTP-SAIFR/IFT-UNESP
Home
Recent advancements in gravitational physics and astrophysics have gathered significant attention, underscored by the Nobel Prizes awarded in 2017 (Weiss, Barish, Thorne), 2019 (Peebles, Mayor, Queloz), and 2020 (Penrose, Genzel, Ghez). Concurrently, we have embarked on an era characterized by astrophysical and cosmological surveys of unparalleled precision, resolution, and cadence. These surveys enable intertwined investigations in galactic, extragalactic astrophysics, and cosmology fields that, although deeply interconnected, have historically been explored through separate avenues with only occasional intersections.
Gravitational wave detections are starting to give invaluable information about stellar mass function and birth rates, which in turn provides insights into galaxy and protogalaxy formation and the boundary conditions for matter that forms exoplanets. Such knowledge also provides a crucial piece of the puzzle in understanding galactic structure formation which has important cosmological consequences.
This school is dedicated to bridging astrophysics and cosmology across different scales by offering fresh perspectives for interpreting recent observations of gravitational waves, black holes, and exoplanets.
There is no registration fee and limited funds are available for travel and local expenses.

Witnessing Quantum Aspects of Gravity in a Lab
September 23 – 27, 2024
São Paulo, Brazil
ICTP-SAIFR/Principia Institute
Home
This prescription for witnessing entanglement certifies gravity as a coherent quantum mediator through simple correlation measurements between two spins: one embedded in each test mass known as a QGEM (quantum gravity induced entanglement of masses) protocol. This workshop will discuss various theoretical and experimental challenges to conceive the QGEM protocol in a lab that will require an unprecedented level of accuracy in witnessing the quantum nature of one of nature’s weakest interactions. Moreover, this workshop will also address other theoretical and experimental endeavors to conceive quantum-gravity phenomenology in several different settings.
This event will be instrumental in fostering exchange and collaboration among a diverse cluster of researchers, including expanding field landscapes and exploring new research directions. By incorporating perspectives from multiple communities, we expect to chart a path toward future trends for foundational physics from the study of quantum gravitational phenomena and their crossing with many different areas of modern physics. Key scientific topics at this intersection of theory and experiment cover the recent program for modeling tabletop tests to probe the quantum-gravitational origin of entanglement of massive objects, studies of analogue gravity in condensed-matter systems, tests of the equivalence principle, studies of the interplay of fundamental symmetries in neutrino oscillations, tests of modification of quantum mechanics in configurations where gravity plays an important role, modified dispersion relations, precision tests of general relativity in astrophysics, effective field theory of general relativity and the search of potential quantum gravity signatures in the investigation of cosmic messengers.
The first part of the workshop will focus on possible quantum experiments, and the second part will focus on theoretical aspects of general relativity.
There is no registration fee and limited funds are available for local expenses.

Minicourse on quantum computing
April 8-10, 2024
São Paulo, Brazil
ICTP-SAIFR/IFT-UNESP
Home
Quantum computing is a growing field where the information is processed by two-levels quantum states known as qubits. Quantum computers offer an intriguing path for a paradigmatic change of computing in the natural sciences and beyond, with the potential for achieving a so-called quantum advantage, namely a significant (in some cases exponential) speed-up of numerical simulations. The rapid development of hardware devices with various realizations of qubits enables the execution of small scale but representative applications on quantum computers.
In this context, we present a basic introduction to quantum computing paradigm, algorithms and software. The minicourse is organized in lectures and hands-on tutorials using quantum computing software (Qibo).
Requirements:
Basic knowledge of quantum mechanics and computer science may help to appreciate the material presented in the minicourse.
Participants are required to bring their computers with Python (>3.9) installed or access to Google Colab during the tutorial sessions.

Second School on Dark Matter and Neutrino Detection
July 8-19, 2024
São Paulo, Brazil
ICTP-SAIFR/IFT-UNESP
Home
In recent years, Dark Matter detection has shifted from a pure astrophysics field to laboratory physics. Currently, several operating experiments are probing the parameter space of Dark Matter properties and a myriad of techniques are being proposed and tested. Another rapidly growing field in experimental physics is Neutrino Detection. Although several of their properties, such as neutrino oscillations, are well established, many unknowns remain. For instance, we still need to know the neutrino mass hierarchy, the theta_23 octant and the CP violation phase. Other fundamental properties remain to be tested, such as the coherent neutrino scattering at the lowest neutrino energies.
These two fields – Dark Matter and Neutrino Detection – are deeply connected. Most Dark Matter experiments rely on this particle though the weak interaction, such that neutrino detection methods have inspired many of the current Dark Matter experiments. Neutrinos are an unavoidable background for Dark Matter detection and upcoming experiments will soon reach the so-called neutrino floor. Also, sterile neutrinos are competitive Dark Matter candidates.
Despite their growing importance, in general, these two topics are very seldom discussed together in physics schools. The aim of the school is to introduce the students to the field of particle Dark Matter and Neutrino Detection, share the excitement on model building and detection methods, and prepare the next generation to contribute to this endeavor.
The school is composed of courses and lectures on advanced topics, with significant time for questions/discussions and practical hands-on activities. The labs which demonstrate techniques used in real experiments are a key part of the school. As far as we know, this is the only school worldwide with experimental labs covering both Dark Matter and Neutrino Detection.
The first week will take place in the IFT-UNESP auditorium and will give a general introduction to the fields of Dark Matter and neutrino physics with a more theoretical focus, providing the basis to address the detection methods. The second week will take place at the Principia Institute and will focus on detection techniques and specific experiments, with most of the afternoon dedicated to experimental work in small groups.
There is no registration fee and limited funds are available for travel and local expenses.
This activity will be preceded by the III Joint ICTP-SAIFR/ICTP-Trieste Summer School on Particle Physics from June 24 to July 5.

Description of Experiments
Virtual Machine: Here
Click here to see tutorial about VM
Click here to see the Required Softwares
EXPERIMENT #1: Sensitivity and exclusion limits for DM & Nu experiments
Dario Rodrigues (UBA, Argentina)
This activity will consist of two parts. The first part will introduce key concepts of statistics necessary for calculating sensitivity and exclusion limits both in neutrino physics and in the search for dark matter. The second part will involve implementing computationally what has been learned in hands-on work.
EXPERIMENT #2: LAr experiment design using Monte Carlo simulations
Franciole Marinho (ITA, Brazil) & Laura Paulucci (UFABC, Brazil)
In this hands-on activity we will explore the development of Monte Carlo simulations with focus on liquid argon experiments using the Geant4 toolkit. After a short introduction to the basic elements needed to run the simulation (description of the geometry, physical and optical properties of the materials, particles interactions) participants will observe particle’s propagation in the simulated media and design analyses producing results based on physical interpretation with simulated data.
EXPERIMENT #3: Particle detection with a CMOS camera
Ana Botti (Fermilab, USA)
CMOS and CCD devices are silicon-pixeled detectors widely implemented in scientific and commercial applications. Despite their primary use as digital cameras, they are also great particle detectors since charge particles produce ionization electrons as they pass through the silicon. In this activity, we will discuss the principles and differences between CMOS and CCD devices, implement CMOS cameras with a Raspberry Pi to measure particle tracks, and discuss their application for dark matter and neutrino detection.
EXPERIMENT #4: Muon veto systems based on plastic scintillators
Matias Rolf Hampel (ITeDA, Argentina)
Muon veto systems act as an active shield to tag any muon-induced activity in particle detection experiments. In this laboratory practical, groups of 2 or 3 students will learn how to build and use such a system. They will operate a setup consisting of plastic scintillators coupled to silicon photomultipliers (SiPMs) through wavelength shifting fibers. The practice will cover fundamental aspects of SiPMs as light detectors, as well as techniques for muon detection using plastic scintillators. Students will acquire and analyze data to estimate the muon detection efficiency of the experimental setup.
EXPERIMENT #5: Particle detection using a silicon pixel detector
Vinicius Franco Lima (UFRJ, Brazil) & Irina Nasteva (UFRJ, Brazil)
This experiment is designed to introduce a pixelated silicon state-of-the-art detection system for x-rays and charged particles, developed at CERN as a spin-off development of the Large Hadron Collider (LHC). A basic understanding of semiconductor pixel detectors and particle interaction with matter and detection will be given by calibrating the detector with known x-ray sources. A variety of software tools will be used for data acquisition, detector calibration and data analysis.
At Universidade de São Paulo:
EXPERIMENT #6: Characterisation of Silicon PhotoMultipliers for astroparticle physics applications
Simone Sanfilippo (INFN, Italy)
The students will be familiar with the standard procedure used in many applications of neutrino and dark matter search about the characterisation of Silicon PhotoMultipliers (SiPMs). In particular they will learn how to extract breakdown voltage from I-V curves and how to look at the single-electron spectrum from the acquired data.
EXPERIMENT #7: Pulse-shape discrimination for gamma-neutron separation
Edivaldo Moura Santos (USP, Brazil) & Nikolas Kemmerich (USP, Brazil)
Plastic or liquid scintillators are very powerful fast neutron detectors and have been extensively employed in nuclear and particle physics applications. For example, in experiments such as those designed to measure the response of liquefied noble gases (like Liquid Argon LAr) to low-energy nuclear recoils induced by neutrons, they are used as the main neutron detectors. Even in the presence of ubiquitous gamma radiation, scintillators show excellent photon-neutron separation power through the Pulse Shape Discrimination (PSD) technique. In this laboratory activity, students will study the time response of a scintillator detector to a gamma source and learn to construct such pulse-shape parameters using an experimental setup that includes nanosecond time-resolution electronics. Finally, neutron and gamma population data will be analyzed to demonstrate separation power.
EXPERIMENT #8: Compton edge-based energy resolution measurements with a coincidence setup
Nikolas Kemmerich (USP, Brazil) & Edivaldo Moura Santos (USP, Brazil)
In this laboratory activity, students will measure the energy resolution of a scintillator detector using gamma rays. This will be possible due to the ability of photons to Compton scatter electrons in the scintillator target material and then be detected in temporal coincidence by a reference detector with known energy calibration. The setup will allow students to familiarize themselves with standard acquisition electronics in nuclear and particle physics as well as coincidence trigger logic. The reference detector will be a high-resolution solid-state device (HPGe High Purity Germanium Radiation Detector) working at cryogenic temperatures to provide a reference energy measurement based on the photoelectric effect. Students should work on the determination of the energy resolution of the scintillator by analyzing the scintillator pulse height distribution acquired in coincidence with the HPGe detector.
EXPERIMENT #9: Gamma Spectrometry using Semiconductor Detectors
Guilherme S. Zahn (IPEN-CNEN/SP, Brazil), Paulo Sérgio C. da Silva (IPEN-CNEN/SP, Brazil) & Frederico A. Genezini (IPEN-CNEN/SP, Brazil)
The precise measurement of high energy photons is of paramount importance in many fields of both basic and applied sciences. In this sense, the high resolution gamma ray spectroscopy performed using semiconductor detectors, where transitions with very similar energies can be precisely discriminated, is a very powerful tool. In this experiment, students will learn the basic concepts on the measurement of photons using semiconductor detectors, then will have a hand-on experience on the use of a high-resolution high purity germanium detector (HPGe), from the initial calibration of the system to actual measurements of standard sources and also of real-world samples, where the high complexity of the spectrum presents an additional challenge. Additionally, the ubiquitous gamma-ray background will be discussed, and students will be offered the possibility to perform a thorough analysis of the transitions found in the environmental radiation.

Minicourse on perturbative and nonperturbative treatment of quantum gravity problems
May 20-24, 2024
ICTP-SAIFR, São Paulo, Brazil
IFT-UNESP Auditorium
Home
The event is intended as a discussion of specific problems of quantum gravity, with the focus on non-traditional, i.e. qualitatively new, aspects and non-perturbative approaches. The general goal is to explain (or at least better understand) the main contradiction of quantum gravity, which is that the theory to be renormalizable always has higher derivatives, and therefore contains massive higher-derivative ghosts. This leads to classical and quantum instabilities and, in the quantum theory, the removal of ghosts from the spectrum violates the unitarity of the S-matrix. No known approaches to quantum gravity resolve the problem of ghosts in a satisfactory way, which we see as an indication that qualitatively new ideas need to be implemented.
Along with the planned discussions of the aforementioned issues, we will offer three introductory courses on quantum gravity. The mini-course of Prof. Asorey will review quantum gravity from a wide perspective, covering many different subjects. The mini-course by Prof. Menezes will provide an introduction to the basic notions and models of theories with higher derivatives. Finally, the mini-course of Prof. Shapiro will discuss the pertinent issue of decoupling theorems in gravity, which is relevant for determining in which theories of gravity we may expect a universal IR limit, i.e., quantum GR.
The necessary preliminary preparation of participants in this event includes standard courses of general relativity and quantum field theory.
There is no registration fee and limited funds are available for local expenses.
