Conditions for the validity of the quantum Langevin equation
J. Frenkel, J. C. Taylor
From microscopic models, a Langevin equation can in general be derived only as an approximation. Two possible conditions to validate this approximation are studied. One is, for a l…
The long wavelength limit of hard thermal loop effective actions
F T Brandt, J Frenkel, J C Taylor
We derive a closed form expression for the long wavelength limit of the effective action for hard thermal loops in an external gravitational field. It is a function of the metric,…
Transport equation and hard thermal loops in noncommutative Yang-Mills theory
F. T. Brandt, Ashok Das, J. Frenkel +2
We show that the high temperature limit of the noncommutative thermal Yang-Mills theory can be directly obtained from the Boltzmann transport equation of classical particles. As an…
Kronecker delta energy terms in thermal field theory
F. T. Brandt, Ashok Das, J. Frenkel +1
We discuss, using the imaginary time method, some aspects of the connection between the Ward identity, the non-analyticity of amplitudes and the causality relation in QED at finite…
High-temperature QCD and the classical Boltzmann equation in curved spacetime
F. T. Brandt, J. Frenkel, J. C. Taylor
It has been shown that the high-temperature limit of perturbative thermal QCD is easily obtained from the Boltzmann transport equation for `classical' coloured particles. We genera…
Nonlinear interaction between electromagnetic fields at high temperature
Fernando T. Brandt, Josif Frenkel, John C. Taylor
The electron-positron `box' diagram produces an effective action which is fourth order in the electromagnetic field. We examine the behaviour of this effective action at high-tempe…
The energy of the high-temperature quark-gluon plasma
F. T. Brandt, J. Frenkel, J. C. Taylor
For the quark-gluon plasma, an energy-momentum tensor is found corresponding to the high-temperature Braaten-Pisarski effective action. The tensor is found by considering the inter…
