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…
