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…
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…
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…
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…
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…
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…
Dephasing-assisted transport in a tight-binding chain with a linear potential
Samuel L. Jacob, Laetitia P. Bettmann, Artur M. Lacerda +4
An environment interacting with a quantum system can enhance transport through the suppression of quantum effects responsible for localization. In this paper, we study the interpla…
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…
Thermodynamics of a continuously monitored double quantum dot heat engine in the repeated interactions framework
Laetitia P. Bettmann, Michael J. Kewming, John Goold
Understanding the thermodynamic role of measurement in quantum mechanical systems is a burgeoning field of study. In this article, we study a double quantum dot (DQD) connected to…
Critical Currents in Conventional Josephson Junctions With Grain Boundaries
Miguel Antonio Sulangi, Laetitia Bettmann, T. A. Weingartner +5
It has been hypothesized that the variation of the critical currents in Nb/Al-AlO/Nb junctions is due to, among other effects, the presence of grain boundaries in the system. M…
Magnetic anisotropy from linear defect structures in correlated electron systems
Mainak Pal, Laetitia Bettmann, Andreas Kreisel +1
Correlated electron systems, particularly iron-based superconductors, are extremely sensitive to strain, which inevitably occurs in the crystal growth process. Built-in strain of t…
