Probing the edge between integrability and quantum chaos in interacting few-atom systems
Thomás Fogarty, Miguel Ángel García-March, Lea F. Santos +1
Interacting quantum systems in the chaotic domain are at the core of various ongoing studies of many-body physics, ranging from the scrambling of quantum information to the onset o…
A many-body heat engine at criticality
Thomás Fogarty, Thomas Busch
We show that a quantum Otto cycle in which the medium, an interacting ultracold gas, is driven between a superfluid and an insulating phase can outperform similar single particle c…
A Feshbach engine in the Thomas-Fermi regime
Tim Keller, Thomás Fogarty, Jing Li +1
Bose-Einstein condensates can be used to produce work by tuning the strength of the interparticle interactions with the help of Feshbach resonances. In inhomogeneous potentials, th…
In situ thermometry of a cold Fermi gas via dephasing impurities
Mark T. Mitchison, Thomàs Fogarty, Giacomo Guarnieri +3
The precise measurement of low temperatures is a challenging, important and fundamental task for quantum science. In particular, in-situ thermometry is highly desirable for cold at…
Orthogonality Catastrophe as a Consequence of the Quantum Speed Limit
Thomás Fogarty, Sebastian Deffner, Thomas Busch +1
A remarkable feature of quantum many-body systems is the orthogonality catastrophe which describes their extensively growing sensitivity to local perturbations and plays an importa…
Effects of coherence on quantum speed limits and shortcuts to adiabaticity in many-particle systems
Tian-Niu Xu, Jing Li, Thomas Busch +2
We discuss the effects of many-body coherence on the speed of evolution of ultracold atomic gases and the relation to quantum speed limits. Our approach is focused on two related s…
