New time contour for equilibrium real-time thermal field theories.
A new time contour is used to derive real-time thermal field theory. Unlike previous path integral approaches, no contributions to the generating functional are dropped. PACS number: 11.10-z In the path integral approach to equilibrium thermal field theories, one is calculating thermal expectation values, typically ΓC(τ1, τ2, ..., τN) = Tr{eΦ−βHTCφ1(τ1)φ2(τ2)...φN(τN )}/Tr{eΦ−βH}. (1) Here Tc i...
متن کاملOn the Finite Temperature Formalism in Integrable Quantum Field Theories
Two different theoretical formulations of the finite temperature effects have been recently proposed for integrable field theories. In order to decide which of them is the correct one, we perform for a particular model an explicit check of their predictions for the one–point function of the trace of the stress–energy tensor, a quantity which can be independently determined by the Thermodynamica...
متن کاملWilson Renormalization Group formulation of Real Time thermal field theories
We apply Renormalization Group techniques to the Real Time formulation of thermal field theory. Due to the separation between the T = 0 and the T = 0 part of the propagator in this formalism, one can derive exact evolution equations for the Green functions describing the effect of integrating out thermal fluctuations of increasing wavelengths, the initial conditions being the renormal-ized Gree...
متن کاملAlgebraic Properties of Thermal Quantum Field Theories
We establish the Schlieder and the Borchers property for thermal field theories. In addition, we provide some information on the commutation and localization properties of projection operators.
متن کاملHard thermal loops in the real-time formalism
We present a systematic discussion of Braaten and Pisarski’s hard thermal loop (HTL) effective theory within the framework of the real-time (Schwinger-Keldysh) formalism. As is well known, the standard imaginary-time HTL amplitudes for hot gauge theory express the polarization of a medium made out of nonabelian charged point-particles; we show that the complete real-time HTL theory includes, in...
