PHYS 744. Finite Temperature Field Theory.

Tools of finite temperature (relativistic) field theory. Thermodynamics, introducing bosonic and fermionic Euclidean path integrals. Pressure in a free theory, the perturbative expansion, thermal masses, and symmetry restoration. Schwinger-Keldysh contour path integral and its perturbative expansion. Collective phenomena such as dispersion corrections, plasma oscillations, Debye screening and Landau damping.
