Giant magnetocaloric effect in magnetoelectric Eu1-xBaxTiO3
Km Rubi, Pawan Kumar, D. V. Maheswar Repaka +3
We report the magnetic entropy change (Delta Sm) in magnetoelectric Eu1-xBaxTiO3 for x = 0.1- 0.9. We find - delta Sm = 11 (40) J/kg.K in x = 0.1 for a field change of 1 (5) Tesla…
Thermal transport across metal-insulator interface via electron-phonon interaction
Lifa Zhang, Jing-Tao Lü, Jian-Sheng Wang +1
The thermal transport across metal-insulator interface can be characterized by electron-phonon interaction through which an electron lead is coupled to a phonon lead if phonon-phon…
Nonlinearity enhanced interfacial thermal conductance and rectification
Lifa Zhang, Juzar Thingna, Dahai He +2
We study the nonlinear interfacial thermal transport across atomic junctions by the quantum self-consistent mean field (QSCMF) theory based on nonequilibrium Green's function appro…
Exchange fluctuation theorem for heat transport between multi-terminal harmonic systems
Bijay Kumar Agarwalla, Huanan Li, Baowen Li +1
We study full counting statistics for transferred heat and entropy production between multi-terminal systems in absence of a finite junction. The systems are modelled as collection…
Spin rectification in thermally driven XXZ spin chain via the spin-Seebeck effect
Juzar Thingna, Jian-Sheng Wang
We study the phenomenon of spin-current rectification in a one-dimensional XXZ spin chain in the presence of a thermal drive. In our model a pure spin current is generated by a tem…
Reduced density matrix for nonequilibrium steady states: A modified Redfield solution approach
Juzar Thingna, Jian-Sheng Wang, Peter Hänggi
We describe a method to obtain the reduced density matrix (RDM) correct up to second order in system-bath coupling in \emph{nonequilibrium} steady state situations. The RDM is obta…
Work distribution under continuous quantum histories
Huanan Li, Jian-Sheng Wang
We present a general scheme to obtain work distribution in closed systems under continuous quantum histories of corresponding "power" operator. The scheme is tested by analytically…
Nonequilibrium Green's function method for quantum thermal transport
Jian-Sheng Wang, Bijay Kumar Agarwalla, Huanan Li +1
This review deals with the nonequilibrium Green's function (NEGF) method applied to the problems of energy transport due to atomic vibrations (phonons), primarily for small junctio…
