Impossibility of Refrigeration and Engine Operation in Minimal Qubit Repeated-Interaction Models
Gabrielle Barsky-Giles, Alessandro Prositto, Matthew Gerry +1
We investigate the operation of a qubit as a quantum thermal device within the repeated interaction framework, allowing for strong system-bath coupling and finite interaction times…
Separation of relaxation timescales via strong system-bath coupling: Dissipative three-level system as a case study
Brett Min, Matthew Gerry, Dvira Segal
We analytically demonstrate that strong system-bath coupling separates the relaxation dynamics of a dissipative quantum system into two distinct regimes: a short-time dynamics that…
Machine learning delta-T noise for temperature bias estimation
Matthew Gerry, Jonathan J. Wang, Joanna Li +3
Delta-T shot noise is activated in temperature-biased electronic junctions, down to the atomic scale. It is characterized by a quadratic dependence on the temperature difference an…
Random walk with horizontal and cyclic currents
Joanna Li, Matthew Gerry, Israel Klich +1
We construct a minimal two-chain random walk model and study the information that fluctuations of the flux and higher cumulants can reveal about the model: its structure, parameter…
Understanding multiple timescales in quantum dissipative dynamics: Insights from quantum trajectories
Matthew Gerry, Michael J. Kewming, Dvira Segal
Open quantum systems with nearly degenerate energy levels have been shown to exhibit long-lived metastable states in the approach to equilibrium, even when modelled with certain Li…
Challenges in molecular dynamics simulations of heat exchange statistics
Jonathan J. Wang, Matthew Gerry, Dvira Segal
We study heat exchange in temperature-biased metal-molecule-metal molecular junctions by employing the LAMMPS atomic molecular dynamics simulator. Generating the nonequilibrium ste…
Random walks on modular chains: Detecting structure through statistics
Matthew Gerry, Dvira Segal
We study kinetic transport through modular networks consisting of alternating domains using both analytical and numerical methods. We demonstrate that the mean velocity is insensit…
Full counting statistics and coherences: fluctuation symmetry in heat transport with the Unified quantum master equation
Matthew Gerry, Dvira Segal
Recently, a "Unified" quantum master equation was derived and shown to be of the Gorini-Kossakowski-Lindblad-Sudarshan (GKLS) form. This equation describes the dynamics of open qua…
Absence and recovery of cost-precision tradeoff relations in quantum transport
Matthew Gerry, Dvira Segal
The operation of many classical and quantum systems in nonequilibrium steady state is constrained by cost-precision (dissipation-fluctuation) tradeoff relations, delineated by the…
Bounds on fluctuations for ensembles of quantum thermal machines
Matthew Gerry, Na'im Kalantar, Dvira Segal
We study universal aspects of fluctuations in an ensemble of noninteracting continuous quantum thermal machines in the steady state limit. Considering an individual machine, such a…
Universal Bounds on Fluctuations in Continuous Thermal Machines
Sushant Saryal, Matthew Gerry, Ilia Khait +2
We study bounds on ratios of fluctuations in steady-state time-reversal heat engines controlled by multi affinities. In the linear response regime, we prove that the relative fluct…
