Enhancing ultracold atomic batteries using many-body resonances
Duc Tuan Hoang, Thomas Busch, Thomás Fogarty
We study the charging performance of a one-dimensional many-body bosonic quantum battery coupled to a harmonic-oscillator charger. In the weak-coupling regime, we show that the bat…
Boosting the performance of a Lipkin-Meshkov-Glick quantum battery via symmetry-breaking quenches or a single-mode bosonic charger
Le Bin Ho, Duc Tuan Hoang, Tran Duong Anh-Tai +3
We explore the operation of quantum batteries in the Lipkin-Meshkov-Glick (LMG) model, when they are charged either through a sudden quench in the magnetic field strength or by cou…
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…
Leveraging quantum statistics to enhance heat engines
Keerthy Menon, Thomas Busch, Thomás Fogarty
A key focus of designing quantum thermal devices is the potential advantage that can be gleaned from genuine quantum effects when compared to classical devices. The recent experime…
Dynamical invariant based shortcut to equilibration in open quantum systems
Mohamed Boubakour, Shimpei Endo, Thomás Fogarty +1
We propose using the dynamical invariant also known as the Lewis-Riesenfeld invariant, to speed-up the equilibration of a driven open quantum system. This allows us to reverse engi…
Quench dynamics in topologically non-trivial quantum many-body systems
Sarika Sasidharan Nair, Giedrius Žlabys, Wen-Bin He +2
We investigate the nonequilibrium dynamics of a groundstate fermionic many body gas subjected to a quench between parameter regimes of a topologically nontrivial Hamiltonian. By fo…
