On quantum phase crossovers in finite systems
Clare Dunning, Katrina E. Hibberd, Jon Links
In this work we define a formal notion of a quantum phase crossover for certain Bethe ansatz solvable models. The approach we adopt exploits an exact mapping of the spectrum of a m…
Quantifying ground state entanglement of the BCS model
Clare Dunning, Jon Links, Huan-Qiang Zhou
The concept of local concurrence is used to quantify the entanglement between a single qubit and the remainder of a multi-qubit system. For the ground state of the BCS model in the…
Quantum dynamics of a model for two Josephson-coupled Bose--Einstein condensates
A. P. Tonel, J. Links, A. Foerster
In this work we investigate the quantum dynamics of a model for two single-mode Bose--Einstein condensates which are coupled via Josephson tunneling. Using direct numerical diagona…
Energy level statistics for models of coupled single-mode Bose--Einstein condensates
Silvio R. Dahmen, Jon Links, Ross H. McKenzie +1
We study the distribution of energy level spacings in two models describing coupled single-mode Bose-Einstein condensates. Both models have a fixed number of degrees of freedom, wh…
