To better understand complex phenomena in neuroscience that occur at a wide range of scales (from the dynamics of single neurons in vitro neuronal cultures to the whole brain), appropriate models, experimental techniques and data analysis techniques are needed.

This school for PhD students and young postdocs will focus on five main areas: nonlinear dynamics, complex networks, data analysis, information theory and machine learning. The school will cover fundamental and applied aspects such as excitability and neuronal dynamics, neural coding, entropy and complexity measures, machine learning and data analysis methods for inferring functional connectivity, methods for characterizing functional networks, etc.

A “student’s presentation” session will be organized on Monday afternoon, where participants will have 3 min to present themselves and explain their research topic. At the end of the school, participants will present group projects based on the tools learned in the school. Besides the lectures, tutored sessions and discussions will be organized to help participants with the development of the group projects.

There is no registration fee and limited funds are available for travel and local expenses.

Gauge theories and gravitational interactions form the basis of our current understanding of the universe. To realize them in a unified framework is a formidable task, yet common properties have been uncovered through a duality between color and kinematics and the subsequent double-copy perspective. More recently, observations of gravitational waves have triggered a surge of research in this field, and modern amplitudes-based techniques have been very useful for the general relativistic two-body problem.

In this advanced school, students will learn modern techniques for computing scattering amplitudes which are not usually seen in standard graduate courses, and will interact with renowned researchers in the field. Selected students will be invited to participate in the “Gravitational Waves meet Amplitudes in the Southern Hemisphere” program which follows the two-week school.

There is no registration fee and limited funds are available for travel and local expenses.

  • Thales Azevedo (IF/UFRJ, Brazil)
  • Nathan Berkovits (ICTP-SAIFR & IFT/UNESP, Brazil)

I’ve prepared some lecture notes that should cover a basic introduction to linearized GR, EFT approach to the gravitational two body problem and some phenomenology/data analysis overview.
You can find them at
A somehow detailed list of topics that I intend to cover is (the last topic about NANOgrav is not yet in the notes, writing now about it):
* Astronomical/cosmological scales and GR
* Orbital decay of binary systems
* Linearized GR and counting of degrees of freedom
* Green functions
* EM tensor of GWs
* Multipole expansions at the level of the e.o.m.
* Quadrupole formula and beyond
* Lagrangiand formulation, conservative and dissipative physics
* Near and far zones, gravitational non-linearities
* Interaction with the detector
* Building a GWform, matched filtering
* Elements of cosmology/NANOgrav detection of GWs

Jaroslav Trnka: Here is a (preliminary) description of lectures:
Overview of amplitudes: introduction to on-shell amplitudes, spinor helicity formalism, three-point amplitudes, factorization, Yang-Mills amplitudes, color-ordering, BCFW recursion relations, open challenges, glimpse of the Amplituhedron
Here is a list of some reading but the lectures will be self-contained:
– SAGEX review: https://arxiv.org/abs/2203.13011 and individual overview lectures
– amplitudes book by Elvang and Huang: https://arxiv.org/abs/1308.1697
– lectures by Lance Dixon: https://arxiv.org/abs/1310.5353
– lectures by Clifford Cheung: https://arxiv.org/abs/1708.03872

Week 2:

Radu Roiban: for a “big picture” snapshot as of the middle of last year, I would suggest https://arxiv.org/abs/2204.05194 and
for a slightly more technical one https://arxiv.org/abs/2203.13013.
For explicit use of some of the methods that I will cover, I would suggest looking over
https://arxiv.org/abs/1808.02489 and https://arxiv.org/abs/1908.01493

Abstract:

Recent development revealed a close connection between a certain classical limit of scattering amplitudes in quantum field theory and classical interactions of massive bodies. In these lectures we will review this connection for conservative gravitational dynamics. Topics that will be discussed are:

– perturbative expansions of two-body interactions
– classical interaction potential from scattering amplitudes in nonrelativistic quantum mechanics beyond leading order
– classical regime of scattering amplitudes — tree level
– Hamiltonian and radial action: general picture
– tree-level/leading order/1PM/1PL illustration
– classical regime of scattering amplitudes — loop level: identification of the relevant contributions vs generalized unitarity
– one-loop/next-to-leading order/2PM illustration
– aspects of resummation of the radial action
– comments on beyond 2PM
– other effects — tidal, spin (if time allows)

The AdS/CFT correspondence, first proposed by Juan Maldacena in 1997, relates non-gravitational theories with a gravitational theory in a higher dimension, the correspondence being holographic in nature. Since it is a non-perturbative duality, such that a weakly coupled model on one side corresponds to a strongly coupled (hard to solve) one on the other, it has been applied to understand a multitude of interesting strongly coupled problems in various areas of theoretical physics. The various areas represented at the Holography@25 event will include: formal aspects, definition and tests; applications to QCD and nuclear physics; applications to condensed matter theory; applications to black holes, information, chaos and complexity; and applications to integrability.

The Holography@25 event will take place at the ICTP-SAIFR in São Paulo, Brazil, and will include a School (June 5-13, 2023) for graduate students and a Workshop (June 14-17, 2023) for researchers. The event will be preceded by an introductory minicourse on AdS-CFT which can be attended online or in the IFT-UNESP auditorium. The AdS/CFT correspondence, generalized to gauge/gravity duality, or in one word, holography, has become an important tool of theoretical physics, and it is the purpose of the School to familiarize the participants with its methods and applications. The School will be followed by a 4-day workshop celebrating the 25th anniversary of the birth of the AdS/CFT correspondence and will bring together researchers who will describe new advances from all the areas of the correspondence discussed at the School.

There is no registration fee and candidates may apply either for one or both activities.

Organizers:

  • Horatiu Nastase (IFT-UNESP, Brazil)
  • Carlos Nunez (Swansea University, UK)
  • Diego Trancanelli (IF-USP, Brazil and Modena University, Italy)

Physics Opportunities at an Electron-Ion Collider 2023

POETIC 10, the tenth international conference on the ‘Physics Opportunities at an Electron-Ion Collider’, follows POETIC 9 which took place at Lawrence Berkeley National Laboratory in 2019. This meeting was to take place in 2020 but has been postponed due to the pandemic since then.

The primary goal of the conference is to continue the advancement of the field of the future Electron-Ion Collider (EIC) physics which was granted Critical Decision 1 (CD-1) by the U.S. Department of Energy (DOE) and will be built at Brookhaven National Lab in New York. This collider will be a first-of-its-kind research machine and will push the limits of our knowledge of accelerator science, particle detector design, high-performance computing and more.

The main challenges the EIC will address are: the precision 3D imaging of the internal structure of protons and nuclei; solving the mystery of how the quarks and gluons inside the proton combine their spins to generate the proton’s overall spin; the origin of the nucleon’s mass; the search for a color glass condensate, which may be produced for the first time by an EIC, providing deeper insight into gluons and their interactions; in-medium modifications of the nucleon structure functions; and casting fresh light on the mystery of why quarks or gluons can never be observed in isolation and are confined within protons and nuclei.

The topics which will be highlighted at the POETIC 10 conference are:

  • Structure of hadrons: (nuclear) parton distribution functions (PDFs), transverse momentum dependent (TMDs) and generalized parton distributions (GPDs), Distribution Amplitudes (DAs), Double Distributions (DDs).
  • Quantum Chromodynamics at high parton densities and small-x: saturation, evolution, Color Glass Condensate. Fragmentation functions and Jet properties.
  • Complementarity and connections of EIC physics with p+p, p+A and A+A collisions: high-pt processes, diffraction, multi-parton interactions, quark-gluon plasma and colored probes in hot nuclear matter
  • Physics beyond the Standard Model and connections to other areas in physics
  • Future DIS facilities: accelerator and detector developments

There is no registration fee.

The central theme of the program will be the application of particle physics methods to the calculation of processes relevant to gravitational-wave phenomenology.

We intend to bring together both experts and younger theorists from three distinct communities:

– Classical General Relativity, including both analytic and numerical approaches;

– Effective Field Theories;

– Scattering Amplitudes.

We also want to bring theorists into contact with observers and analysis specialists from LIGO-Virgo-KAGRA.

We intend to have one talk a day, with lots of time available for informal discussions and collaboration. The building hosting the program is brand new with comfortable discussion areas, right next to the intended hotel in the tourist center of São Paulo. We hope to have fifteen to twenty people in residence each week.

This activity will be preceded by the School on Modern Amplitude Methods for Gauge and Gravity Theories. Selected students attending the school have the option of remaining as observers.

There is no registration fee.

Gravitational Waves meet Amplitudes in the Southern Hemisphere

Minicourse on the Entropy of Cosmological Perturbations

Written by Nathan on October 17th, 2022. Posted in

October 18, 21 and 27  

ICTP-SAIFR, São Paulo, Brazil

Third floor Meeting Room of IFT-UNESP

Lecturer: Antonio Enea Romano (Antioquia U., Colombia)

Organizer: Riccardo Sturani (ICTP-SAIFR/IFT-UNESP)

 

The theory of cosmological perturbations is of fundamental importance, providing a framework to understand the origin of the inhomogeneities we observe in the Universe. The enhancement of primordial perturbations can induce the production of primordial black holes, which could possibly contribute to the dark matter component, or be related to the production of gravitational waves. The enhancement can be achieved either with multi-field models with entropy, or with models with an ultra-slow roll phase. After reviewing the notion of entropy perturbations in different gauges, and clarifying some misconceptions about the relation between conservation laws and adiabaticity, we show that it is possible to model the effects of entropy on comoving curvature perturbations by appropriately defining a momentum dependent effective sound speed (MESS). This model independent approach is shown to work for multi-fields and modified gravity, and allows to constrain phenomenologically the MESS.

1 Review of first order cosmological perturbations
• Scalar-Vector-Tensor decomposition
• Gauge transformations
• Perturbed Einstein’s equations
2 The momentum effective sound speed (MESS) and entropy of cosmological perturbations
• Adiabaticity definitions and conservation laws : uniform density and co-moving gauge
• Are adiabatic perturbations always conserved? Not if ε decreases sufficiently fast (USR)
• Model independent equation for comoving curvature perturbations ζ
• Model independent definition of momentum effective sound speed (MESS)
3 Applications
• Conservation laws
• Multi-fields inflation
• Modified gravity theories
• Mechanisms for primordial black holes production: USR or MESS

 

 

 

Latin-American School on CTA Science

The Cherenkov Telescope Array (CTA) will be the major global observatory for very high energy gamma-ray astronomy over the next decade and beyond. The scientific program of CTA is rather broad: from understanding the role of relativistic cosmic particles to the search for dark matter. CTA will explore the universe using photons from 20 GeV to 300 TeV and significantly improve the sensitivity of high-energy gamma-ray phenomena.

It will feature two arrays, a southern one being located at the European Southern Observatory (ESO) site in Chile, Atacama desert, and a northern one located at the Roque de los Muchachos Observatory (ORM) site in La Palma, Canary Islands. This combination will make CTA the first ground-based gamma-ray telescope with the capability to observe a large sky fraction. CTA will have telescopes of different sizes, with the large ones reaching 23 meters in diameter. The CTA consortium currently has 1,500 members from more than 150 institutes in 25 countries, 18 of them in Latin America.

Therefore, it is of paramount importance to train Latin-American students about CTA science, and this motivated the first Latin-American School of CTA Science. The school will feature lectures on the following topics:

  • Numerical Tools
  • Dark Matter
  • Fundamental Physics
  • Multi-Messenger.

The lectures will be given by experts on these topics who are familiar with the imaging atmospheric Cherenkov telescopes technique. At the school, the students will be familiarized with theoretical aspects of gamma-ray astronomy and through hands-on activities will learn how to install the codes and familiarize themselves with numerical programs, which are important for CTA science.

There is no registration fee and limited funds are available for travel and local expenses.

II ICTP-SAIFR Condensed Matter Theory in the Metropolis

School on Emergent Phenomena in Non-Equilibrium Quantum Many-Body Systems

Written by Jandira on September 14th, 2022. Posted in

The design of quantum many-body states which elude conventional thermodynamics has become a reality in a number of experimental platforms operating in the far-from-equilibrium regime. This school will gather key experts working on non-equilibrium dynamics ranging from driven open systems to AMO platforms, encompassing interdisciplinary boundaries with high energy physics.

The goal of the school is to provide education both at the basic and advanced level on mainstream themes in current research on non-equilibrium quantum many body systems: (1) dissipative engineering of quantum correlated states at the interface of AMO and solid state; (2) perspectives on theoretical progress in quantum many body information to advance the field beyond the noisy intermediate scale quantum (NISQ) device age; (3) modern ultracold atoms and quantum optics simulators; (4) connections from condensed matter and high energy physics (in particular holography) in the study of scrambling dynamics of quantum information. Our aim is to provide a strong starting package to students interested in taking their first steps in the blossoming research area of quantum many-body dynamics.

There is no registration fee and limited funds are available for travel and local expenses.

Organizers:

  • Rosario Fazio (ICTP-Trieste, Italy)
  • Fernando lemini (Universidade Federal Fluminense, Brazil)
  • Jamir Marino (JGU Mainz, Germany)
  • Mohammad Ali Rajabpour (Universidade Federal Fluminense, Brazil)
