Subtleties in the pseudomodes formalism
Wynter Alford, Laetitia P. Bettmann, Gabriel T. Landi
The pseudomode method for open quantum systems, also known as the mesoscopic leads approach, consists in replacing a structured environment by a set of auxiliary "pseudomodes" subj…
Roadmap on Quantum Thermodynamics
Steve Campbell, Irene D'Amico, Mario A. Ciampini +66
The last two decades has seen quantum thermodynamics become a well established field of research in its own right. In that time, it has demonstrated a remarkably broad applicabilit…
Thermodynamic universality across dissipative quantum phase transitions
Laetitia P. Bettmann, Artur M. Lacerda, Mark T. Mitchison +1
We study finite-time driving across second-order dissipative quantum phase transitions described by Lindblad dynamics. We show that the nonadiabatic entropy production, which quant…
Information geometry of transitions between quantum nonequilibrium steady states
Artur M. Lacerda, Laetitia P. Bettmann, John Goold
In a transition between nonequilibrium steady states, the entropic cost associated with the maintenance of steady-state currents can be distinguished from that arising from the tra…
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…
A resource theoretical unification of Mpemba effects: classical and quantum
Alessandro Summer, Mattia Moroder, Laetitia P. Bettmann +3
The Mpemba effect originally referred to the observation that, under certain thermalizing dynamics, initially hotter samples can cool faster than colder ones. This effect has since…
