Divergences in classical theories at non-zero temperature
Autor: dr Aarts, G.A.P.T., Nauta, B.J., van Weert, C.G.
Publikováno v: Physical Review D. Particles, Fields, Gravitation, and Cosmology, 61(10). American Institute of Physics
The classical approximation provides a non-perturbative approach to time-dependent problems in finite temperature field theory. We study the divergences in hot classical field theory perturbatively. At one-loop, we show that the linear divergences ar

Transversality of logarithmic divergences in the classical SU($N$) self-energy
Autor: Arrizabalaga, A.X., Nauta, B.J., van Weert, C.G.
Publikováno v: Physics Letters B, 491, 214-218. Elsevier
We show that the logarithmic divergences that appear in the classical approximation of the finite temperature SU(N) self-energy are transverse. We use the Ward dentities in linear gauges and the fact that the superficial degree of divergence d of a c
