Pós em Física promove seminário com professor da Universidade de Nice
O Programa de Pós-Graduação em Física da UFSC convida para o seminário “Collisional relaxation of systems of particles with long range interactions”, com o professor Bruno Marcos, da Université de Nice, Sophia Antipolis, França, nesta sexta-feira, 1º de novembro, às 10h, no auditório do Bloco G, Sala 419. A presença é obrigatória para os alunos matriculados na disciplina seminários.
Resumo:
There are many systems which present long range interactions, such gravitational systems, two-dimensional vortices, cold atoms, etc. In this talk, I will start explaining the scenario of their evolution, which consists first in the generic formation of out-of-equilibrium long lived states, called “Quasi Stationary States” and then a (comparatively) very slow relaxation towards thermal equilibrium. Then, I will focus on two topics related to the second part of the evolution: (i) the existence of Quasi Stationary States depending of the range of the interaction and (ii) the validity of the Chandrasekhar approximation in inhomogeneous systems.
