Topologically protected Bell-cat states in a simple spin model
B. Lajci, D. H. J. O'Dell, J. Mumford
We consider the topological properties of the so-called central spin model that consists of identical spins coupled to a single distinguishable central spin which arises in phy…

Gauge potentials and vortices in the Fock space of a pair of periodically driven Bose-Einstein condensates
J. Mumford, D. Kamp, D. H. J. O'Dell
We perform a theoretical study of the coupled dynamics of two species of Bose-Einstein condensates (BECs) in a double well potential where both the tunneling and the interatomic in…

Universal scaling of quantum caustics in the dynamics of interacting particles
Monalisa Singh Roy, Jesse Mumford, D. H. J. O'Dell +1
Recent theoretical studies have predicted the existence of caustics in many-body quantum dynamics, where they manifest as extended regions of enhanced probability density that obey…
