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…
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…
Measuring out-of-time-ordered correlation functions with a single impurity qubit in a bosonic Josephson junction
J. Mumford, W. Kirkby, D. H. J. O'Dell
We calculate the out-of-time-ordered correlation function (OTOC) of a single impurity qubit coupled to fully a connected many-particle system such as a bosonic Josephson junction o…
