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…
