Speaker: Edward Corrigan (York University)

Title: Aspects of classical and quantum integrability

Description: The purpose of these lectures is to give an introduction to some of the ideas that underpin the notion of integrability, both its classical origins and properties within systems with finitely many degrees of freedom or nonlinear two-dimensional field theories such as sine-Gordon or Toda field theory, together with some of the methods used to determine properties of the associated quantum field theories, such as their spectrum of states and scattering. More recently investigated properties of systems with one or two boundaries, or containing impurities or defects will be discussed briefly. It is intended to keep the presentation at a level suitable for those with no previous experience of the topics yet also to provide some reasonably detailed examples alongside a broader perspective.

Complex Systems covers a set of emergent fields represented at ICTP-SAIFR by

Modelling in Mathematical Biology

Roberto A. Kraenkel (IFT-UNESP)

Marcus A.M. de Aguiar (Unicamp)

Paulo I. Prado (IB-USP)

The group works with mathematical models in population biology and is oriented towards applications in ecology and epidemiology. Mathematical techniques are the usual ones from nonlinear dynamics. Recent topics that we have researched are modeling the effects of habitat fragmentation on species abundances and ecological factors affecting malaria epidemics.

Spatiotemporal chaos in Complex Networks

Hilda A. Cerdeira (IFT-UNESP)

Fernando F. Fagundes (USP Sao Paulo)

Koichi Sameshima (USP Sao Paulo)

Current research includes synchronization of chaotic systems; applications of techniques of complexity theory to the search of patterns on data from neurological diseases and financial markets.

The field of Condensed Matter Physics is where basic science and applications meet. The combined effects of quantum mechanics and Coulomb interactions between a large number of particles lead to the formation of basic building blocks in nature that when put together give rise to the rich phenomena that we see around us in our daily life. Our drive for ever smaller electronic devices have led to technological breakthroughs giving us an unique opportunity to observe and study the exotic quantum behavior of ultra-clean crystalline systems and low-dimensional nanometer sized electronic devices. Researchers at IFT-UNESP are working to develop a deeper theoretical understanding of the formation and the transport properties of these exciting new systems, which can provide further insights for future materials.

Current research topics include

1) Density Functional Theory applied to atoms molecules and solids

2) Electronic and transport properties of Nanoscopic systems

3) Quantum phase transitions in strongly correlated systems.

4) Effects of disorder in low-dimensional electronic systems.

Researchers at IFT-UNESP include:

Alexandre Reily Rocha

Recently there have been tremendous developments in the field of cosmology. The main areas of research range from theoretical to observational cosmology and astrophysics, galaxy surveys, theories of modified gravity, galaxy clusters, inflation and the cosmic microwave background.

Research in this area is concerned with understanding strongly interacting
matter in the light of the fundamental theory of quarks and gluons, quantum
chromodynamics (QCD). The strong interaction is responsible for nearly all visible
mass of the universe, and hadronic reactions shape structures that range from nuclei
to stars.

Current research topics address a broad range of problems concerned with the
confinement of quarks and gluons, the origin of the masses of the hadrons, and the
properties of the matter produced in high-energy heavy-ion collisions. A non-exhaustive
list of research topics includes:

1) Dynamics of phase transitions in QCD; equilibrium and nonequlibrium field theory
2) Electroweak properties of hadrons
3) Lattice field theory
4) Models of nonperturbative QCD; effective meson-baryon models
5) Nuclear many-body theories
6) Relativistic heavy-ion physics; quark-gluon plasma
7) Tests and consequences of fundamental symmetries
