Abstract

The study of phase transitions and critical phenomena is of great importance,since it allows to understand the underlying mechanisms of matter complexity,e. g., the Anderson-Higgs mechanism of mass generation.In this project, we are interested in non-equilibrium phase transitions to an absorbing state.Models displaying this kind of phase transition are defined by its transition rates among its different statesand have a set of (absorbing) states in which the system remains trapped.These models have seen applications in periodic driven suspensions and in the dynamics of superconductor vortices, to cite a few.Real systems contains spatial (spatial disorder) and temporal (temporal disorder) fluctuationsthat can drastically affect the system critical behavior and change its universality class.These changes can occur even with the least amount of disorder.We intend to extend the understanding of the critical behavior induced by disorderby studying (i) the effects of disorder in the phase transition of non-equilibrium models, and(ii) the combined effects of both spatial and temporal disorder.This project is made in collaboration with Drs. Mário J. de Olivera and Carlos E. Fiore, from Instituto de Física da USP,and with Dr. Thomas Vojta, from Missouri S & T.
