RESUMO:

In this work we will focus in statistical physics applied to problems of Bose-Einstien condensation at finite temperatures. We begin by a brief introduction to the classical methods, already well established by fundamental courses. Afterwards, starting from a kinetic theory, we will obtain the equations of motion for the atoms in the condensate state, as well as for the Bogoliubov quasiparticles of the thermal cloud of excited atoms. Through this kinetic description, we will also obtain, from quantum principles of quantum mechanics, the Born-Bogoliubov-Green-Kirkwood-Ygon (BBGKY) hierarchy, which can be truncated to obtain the Boltzmann-Vlasov Equation. Finally, we will use the same microscopic principles to study the damping of collective excitations of the Bose-Einstein condensate in the thermal regime.
