Thermo Field Dynamics for Quantum Fields with Continuous Mass Spectrum applied to Nuclear Physics
TLDR
Transport coefficients are obtained by incorporating a gauge principle into thermo field dynamics of inhomogeneous systems in this paper, where neither imaginary time arguments nor perturbation theory in powers of a coupling constant are used in the calculation.Abstract:
Transport coefficients are obtained by incorporating a gauge principle into thermo field dynamics of inhomogeneous systems In contrast to previous derivations, neither imaginary time arguments nor perturbation theory in powers of a coupling constant are used in the calculation Numerical values are calculated for the pion component in hot nuclear matterread more

Advances in perturbative thermal field theory
Ulrike Kraemmer,Anton Rebhan +1 more
TL;DR: The progress in the last decade in perturbative quantum field theory at high temperatures and densities, made possible by the use of effective field theories and hard thermal/dense loop resummations in ultrarelativistic gauge theories, is reviewed in this paper.

Transport equations for chiral fermions to order ℏ and electroweak baryogenesis: Part II
TL;DR: In this article, the second in a series of two papers, the authors used a model Lagrangean, in which fermions couple to scalars through Yukawa interactions and approximate the self-energies by the one-loop expressions, and computed the CP-violating contributions to both the scalar and the fermionic collision term.

Supersymmetric CP violating currents and electroweak baryogenesis

TL;DR: In this article, the CP-violating currents of the right-handed stops and higgsinos, induced by the presence of non-trivial vacuum expectation values of the Higgs fields within the context of the minimal supersymmetric extension of the Standard Model (MSSM), were computed using the Keldysh formalism.
Journal ArticleDOI
Electroweak baryogenesis and low energy supersymmetry
TL;DR: In this paper, the baryon asymmetry was computed assuming the presence of non-trivial CP-violating phases in the parameters associated with the left-right stop mixing term and the Higgsino mass μ.

Statistical-Mechanical Theory of Irreversible Processes : I. General Theory and Simple Applications to Magnetic and Conduction Problems
TL;DR: In this paper, a general type of fluctuation-dissipation theorem is discussed to show that the physical quantities such as complex susceptibility of magnetic or electric polarization and complex conductivity for electric conduction are rigorously expressed in terms of timefluctuation of dynamical variables associated with such irreversible processes.

Brownian Motion of a Quantum Oscillator
TL;DR: In this paper, an action principle technique for the direct computation of expectation values is described and illustrated in detail by a special physical example, the effect on an oscillator of another physical system, which has the advantage of combining immediate physical applicability (e.g., resistive damping or maser amplification of a single electromagnetic cavity mode) with a significant idealization of the complex problems encountered in many particle and relativistic fieldtheory.
