  • Cesar Augusto Linhares da Fonseca Junior

Research work in two main lines: Condensed Matter and Out of equilibrium statistical mechanics. Related with condensed matter, the focus is strongly correlated electronic systems, acting mainly on the following topics: Quantum Hall Effect, Superconductivity, Bose-Einstein Condensation, Quantum Fluids, Classical and quantum phase transitions and topological states of matter. Related with statistical mechanics, the focus is on stochastic systems, acting mainly on the following topics: noise-induced phase transitions, stochastic resonance, applications to climatic problems. The field theory techniques used are mainly: gauge theories, bosonization, renormalization group and computational simulations.

Research work with models for the description of non-perturbative phenomena in quantum field theory. Main topics of interest are: duality, confinement, quantization of non-abelian gauge theories, Gribov problem, Higgs mechanism, topological defects, Julia-Toulouse defect condensation mechanism, theories involving spatio-temporal non-commutativity, Lorentz invariance violation, field theories with topological terms (Maxwell-Chern-Simons) and ADS / CFT correspondence.

Research work with emphasis on quantum field theory under external conditions (temperature, chemical potential and external fields). with applications in phase transitions in general (in effective models for quantum cromodynamics, hadron physics and phase transitions in particle physics models), the study of the nonequilibrium dynamics in field theory and the study of bosonic and fermionic systems at reduced dimensions, with applications to condensed matter physics.
