Two problems in thermal field theory

open access: yes, 2000
In this talk, I review recent progress made in two areas of thermal field theory. In particular, I discuss various approaches for the calculation of the quark gluon plasma thermodynamical properties, and the problem of its photon production rate.Comment:

Collective coherent population trapping in a thermal field [PDF]

open access: yes, 2006
We analyzed the efficiency of coherent population trapping (CPT) in a superposition of the ground states of three-level atoms under the influence of the decoherence process induced by a broadband thermal field. We showed that in a single atom there is no

Transient first-order interference of two independent thermal light beams [PDF]

open access: yes, 2013
By analyzing the first-order interference of two independent thermal light beams with both classical and quantum theories, we conclude that it is impossible to observe the transient first-order interference pattern by superposing two independent thermal ...

Dynamics of entanglement of qubits in the three-qubit Tavis — Cummings model with dipole-dipole interaction

open access: yesВестник Самарского университета: Естественнонаучная серия
The article studies the dynamics of pairwise entanglement of three qubits, two of which are trapped in a resonator and interact with a single-mode ideal resonator through single-photon transitions, and the third qubit is outside the resonator. This takes

Thermal mean-field theories

open access: yesThe Journal of Chemical Physics
Several closely related ab initio thermal mean-field theories for fermions, both well-established and new ones, are compared with one another at the formalism level and numerically. The theories considered are Fermi–Dirac theory; thermal Hartree–Fock (HF) theory; two modifications of the thermal single-determinant approximation of Kaplan and Argyres ...

Coupled Fluid-Thermal Analysis for Induction Motors with Broken Bars Operating under the Rated Load

open access: yesEnergies, 2018
Thermal stress of the rotor in a squirrel cage induction motor is generated due to the temperature rise, it is also one of the factors causing the broken bar fault because the structure of the rotor would be destroyed if the stress of the rotor bars ...

Thermal amplification of field-correlation harvesting

open access: yes, 2013
We study the harvesting of quantum and classical correlations from a hot scalar field in a periodic cavity by a pair of spatially separated oscillator-detectors.
