Exact dynamics of interacting qubits in a thermal environment: Results beyond the weak coupling limit
Lian-Ao Wu, Claire X. Yu, Dvira Segal
We demonstrate an exact mapping of a class of models of two interacting qubits in thermal reservoirs to two separate spin-bath problems. Based on this mapping, exact numerical simu…

Theory of quantum energy transfer in spin chains: From superexchange to ballistic motion
Claire X. Yu, Lian-Ao Wu, Dvira Segal
Quantum energy transfer in a chain of two-level (spin) units, connected at its ends to two thermal reservoirs, is analyzed in two limits: (i) In the off-resonance regime, when the…

Nonlinear quantum heat transfer in hybrid structures: Sufficient conditions for thermal rectification
Lian-Ao Wu, Claire X. Yu, Dvira Segal
We present a unified description of heat flow in two-terminal hybrid quantum systems. Using simple models, we analytically study nonlinear aspects of heat transfer between various…
