Anomalous discharging of quantum batteries: the ergotropic Mpemba effect
Ivan Medina, Oisín Culhane, Felix C. Binder +2
Anomalous thermal relaxation is ubiquitous in nonequilibrium statistical mechanics. An emblematic example of this is the Mpemba effect, where an initially ``hot'' system cools fast…
Hilbert subspace ergodicity
Leonard Logaric, John Goold, Shane Dooley
Ergodicity has been one of the fundamental concepts underpinning our understanding of thermalization in isolated systems since the first developments in classical statistical mecha…
Anomalous transport in U(1)-symmetric quantum circuits
Alessandro Summer, Alex Nico-Katz, Shane Dooley +1
In this work we investigate discrete-time transport in a generic U(1)-symmetric disordered model tuned across an array of different dynamical regimes. We develop an aggregate quant…
Quantum master equation from the eigenstate thermalization hypothesis
Peter O'Donovan, Philipp Strasberg, Kavan Modi +2
We use the eigenstate thermalization hypothesis to derive a quantum master equation for a system weakly coupled to a chaotic finite-sized bath prepared in a pure state. We show tha…
Dynamical simulations of many-body quantum chaos on a quantum computer
Laurin E. Fischer, Matea Leahy, Andrew Eddins +16
Quantum circuits with local unitaries have emerged as a rich playground for the exploration of many-body quantum dynamics of discrete-time systems. While the intrinsic locality mak…
Information geometry approach to quantum stochastic thermodynamics
Laetitia P. Bettmann, John Goold
Recent advancements have revealed new links between information geometry and classical stochastic thermodynamics, particularly through the Fisher information (FI) with respect to t…
Thermodynamics of photoelectric devices
Samuel L. Jacob, Artur M. Lacerda, Yonatan Dubi +1
We study the nonequilibrium steady state thermodynamics of a photodevice which can operate as a solar cell or a photoconductor, depending on the degree of asymmetry of the junction…
Can Quantum Computers Do Nothing?
Alexander Nico-Katz, Nathan Keenan, John Goold
Quantum computing platforms are subject to contradictory engineering requirements: qubits must be protected from mutual interactions when idling ('doing nothing'), and strongly int…
Demonstration of energy extraction gain from non-classical correlations
Alexander Stahl, Michael Kewming, John Goold +3
Within the framework of microscopic thermodynamics, correlations can play a crucial role for energy extraction. Our work sheds light on this connection by demonstrating that entang…
Quantum stochastic thermodynamics in the mesoscopic-leads formulation
Laetitia P. Bettmann, Michael J. Kewming, Gabriel T. Landi +2
We introduce a numerical method to sample the distributions of charge, heat, and entropy production in open quantum systems coupled strongly to macroscopic reservoirs, with both te…
Universal energy fluctuations in inelastic scattering processes
Samuel L. Jacob, John Goold, Gabriel T. Landi +1
Quantum scattering is used ubiquitously in both experimental and theoretical physics across a wide range of disciplines, from high-energy physics to mesoscopic physics. In this wor…
Thermodynamics of the quantum Mpemba effect
Mattia Moroder, Oisín Culhane, Krissia Zawadzki +1
We investigate the quantum Mpemba effect from the perspective of non-equilibrium quantum thermodynamics by studying relaxation dynamics of quantum systems coupled to a Markovian he…
