Supersymmetry in Thermo Field Dynamics
نویسندگان
چکیده
By considering the enlarged thermal system including the heat bath, it is shown that this system has supersymmetry which is not broken at finite temperature. The superalgebra is constructed and the Hamiltonian is expressed as the anti-commutator of two kinds of super charges. With this Hamiltonian and the thermal vaccum | 0(β) >, this supersymmetry is found to be preserved.

A Second Supersymmetry in Thermo Field Dynamics
This article is an extension of the work done in [1] by R. Parthasarathy and R. Sridhar. There they consider supersymmetry in an enlarged thermal system (in a thermo field dynamic formulation) and show that this supersymmetry is not broken at finite temperature. Here we show, using an SU(1, 1) R-symmetry, that this system obeys a second supersymmetry. In addition, we proceed to see that this ne...
متن کاملAtomic Radiative Transitions in Thermo Field Dynamics
In this work we study the energy exchange between an atomic system and a thermal radiation field, using the Dalibard, Dupont-Roc and Cohen-Tannoudji (DDC) construct, incorporating temperature effects to the eigenstates of the radiation field operator through the electromagnetic propagator of Thermo Field Dynamics in the Coulomb gauge. We also discuss the stability of the atomic system at finite...

متن کاملSensitivity analysis of dependency of working fluid thermo-dynamics properties to temperature on performance of Gama-type Stirling engine
This research proposes the effect of temperature variation in the Prandtl number on the power, the efficiency and the heat loss of the Gama-type Stirling engine. It should be noted that the Prandtl number included the viscosity, the thermal conductivity coefficient and the specific heat at constant pressures of the working fluid, which the temperature dependency of such first two thermo-dynamic...
