Anomalous Heat Transfer in Nonequilibrium Quantum Systems

Teng Ma, Jing-Ning Zhang, Yuan-Sheng Wang +2

Anomalous heat transfer (AHT), a process by which heat spontaneously flows from a cold system into a hot one, superficially contradicts the Clausius statement of the second law of…

Adiabatic-impulse approximation in non-Hermitian Landau-Zener Model

Xianqi Tong, Gao Xianlong, Su-peng Kou

We investigate the transition from PT-symmetry to PT-symmetry breaking and vice versa in the non-Hermitian Landau-Zener (LZ) models. The energy is generally complex, so the relaxat…
