Quantum statistical correlations in thermal field theories: boundary effective theory
(American Physical Society, 2010-09-08)
Thermal field dynamics and bialgebras
(1997)
In thermal field dynamics, thermal states are obtained from restrictions of vacuum states on a doubled field algebra. It is shown that the suitably doubled Fock representations of the Heisenberg algebra do not need to be ...
Thermal conductivity of hot pionic medium due to pion self-energy for pi sigma and pi rho loops
(World Scientific Publ Co Pte Ltd, 2015-07-01)
The thermal conductivity of pionic medium has been evaluated with the help of its standard expression from the relaxation time approximation, where inverse of pion relaxation time or pion thermal width has been obtained ...
The Scattering of Phonons by Infinitely Long Quantum Dislocations Segments and the Generation of Thermal Transport Anisotropy in a Solid Threaded by Many Parallel Dislocations
(MDPI, 2020)
A canonical quantization procedure is applied to the interaction of elastic waves-phonons-with infinitely long dislocations that can oscillate about an equilibrium, straight line, configuration. The interaction is implemented ...
The g-theorem and quantum information theory
(Springer, 2016-10)
We study boundary renormalization group flows between boundary conformal field theories in 1 + 1 dimensions using methods of quantum information theory. We define an entropic g-function for theories with impurities in terms ...
