Dephasing-enhanced performance in quasiperiodic thermal machines
Cecilia Chiaracane, Archak Purkayastha, Mark T. Mitchison +1
Understanding and controlling quantum transport in low-dimensional systems is pivotal for heat management at the nanoscale. One promising strategy to obtain the desired transport p…
Thermodynamics of decoherence
Maria Popovic, Mark T. Mitchison, John Goold
We investigate the nonequilibrium thermodynamics of pure decoherence. In a pure decoherence process, the system Hamiltonian is a constant of motion and there is no direct energy ex…
Robust nonequilibrium edge currents with and without band topology
Mark T. Mitchison, Ángel Rivas, Miguel A. Martin-Delgado
We study two-dimensional bosonic and fermionic lattice systems under nonequilibrium conditions corresponding to a sharp gradient of temperature imposed by two thermal baths. In par…
Multipartite quantum correlations in a two-mode Dicke model
Rodolfo Soldati, Mark T. Mitchison, Gabriel T. Landi
We analyze multipartite correlations in a generalized Dicke model involving two optical modes interacting with an ensemble of two-level atoms. In particular, we examine correlation…
Time periodicity from randomness in quantum systems
Giacomo Guarnieri, Mark T. Mitchison, Archak Purkayastha +3
Many complex systems can spontaneously oscillate under non-periodic forcing. Such self-oscillators are commonplace in biological and technological assemblies where temporal periodi…
Taking the temperature of a pure quantum state
Mark T. Mitchison, Archak Purkayastha, Marlon Brenes +2
Temperature is a deceptively simple concept that still raises deep questions at the forefront of quantum physics research. The observation of thermalisation in completely isolated…
Out-of-time-order correlations and the fine structure of eigenstate thermalisation
Marlon Brenes, Silvia Pappalardi, Mark T. Mitchison +2
Out-of-time-order correlators (OTOCs) have become established as a tool to characterise quantum information dynamics and thermalisation in interacting quantum many-body systems. It…
