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…

Spin-orbit coupling in the presence of strong atomic correlations

Ayaka Usui, Thomás Fogarty, Steve Campbell +2

We explore the influence of contact interactions on a synthetically spin-orbit coupled system of two ultracold trapped atoms. Even though the system we consider is bosonic, we show…

Driving interactions efficiently in a composite few-body system

Alan Kahan, Thomás Fogarty, Jing Li +1

We study how to efficiently control an interacting few-body system consisting of three harmonically trapped bosons. Specifically we investigate the process of modulating the interp…

Graded-index optical fiber emulator of an interacting three-atom system: illumination control of particle statistics and classical non-separability

M. A. Garcia-March, N. L. Harshman, H. da Silva +4

We show that a system of three trapped ultracold and strongly interacting atoms in one-dimension can be emulated using an optical fiber with a graded-index profile and thin metalli…
