The asymmetric quantum Rabi model and generalised Pöschl-Teller potentials
Kai-Long Guan, Zi-Min Li, Clare Dunning +1
Starting with the Gaudin-like Bethe ansatz equations associated with the quasi-exactly solved (QES) exceptional points of the asymmetric quantum Rabi model (AQRM) a spectral equiva…
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…
