Four-Point Spectral Functions and Ward Identities in Hot QED
Hou Defu, M. E. Carrington, R. Kobes +1
We derive spectral representations for the different components of the 4-point function at finite temperature in the real time formalism in terms of five real spectral densities. W…
Thermalization and Lyapunov Exponents in the Yang-Mills-Higgs Theory
U. Heinz, C. Hu, S. Leupold +2
We investigate thermalization processes occurring at different time scales in the Yang-Mills-Higgs system at high temperatures. We determine the largest Lyapunov exponent associate…
The Plasmon in Hot Theory
Enke Wang, Ulrich Heinz
We study the 2-loop resummed propagator in hot theory. The propagator has a cut along the whole real axis in the complex energy plane, but for small , the spectral dens…
Spectral functions for composite fields and viscosity in hot scalar field theory
Enke Wang, Xiaofei Zhang, Ulrich Heinz
We derive a spectral representation for the two-point Green function for arbitrary composite field operators in Thermo Field Dynamics (TFD). A simple way for calculating the spectr…
