Interaction enhanced quantum heat engine
Mohamed Boubakour, Thomás Fogarty, Thomas Busch
We study a minimal quantum Otto heat engine, where the working medium consists of an interacting few-body system in a harmonic trap. This allows us to consider the interaction stre…
Entropy of the quantum work distribution
Anthony Kiely, Eoin O'Connor, Thomás Fogarty +2
The statistics of work done on a quantum system can be quantified by the two-point measurement scheme. We show how the Shannon entropy of the work distribution admits a general upp…
Making statistics work: a quantum engine in the BEC-BCS crossover
Jennifer Koch, Keerthy Menon, Eloisa Cuestas +5
Heat engines convert thermal energy into mechanical work both in the classical and quantum regimes. However, quantum theory offers genuine nonclassical forms of energy, different f…
Quantum control and quantum speed limits in supersymmetric potentials
Christopher Campbell, Jing Li, Thomas Busch +1
Supersymmetry allows one to build a hierarchy of Hamiltonians that share the same spectral properties and which are pairwise connected through common superpotentials. The iso-spect…
Nonequilibrium many-body dynamics in supersymmetric quenching
Christopher Campbell, Thomás Fogarty, Thomas Busch
We study the dynamics induced by quenching an ultracold quantum many-body system between two supersymmetric Hamiltonians. Such a quench can be created by carefully changing the ext…
Few-body Bose gases in low dimensions -- a laboratory for quantum dynamics
S. I. Mistakidis, A. G. Volosniev, R. E. Barfknecht +5
Cold atomic gases have become a paradigmatic system for exploring fundamental physics, which at the same time allows for applications in quantum technologies. The accelerating deve…
