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…
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…
Quantum phase transitions and magnetization of an integrable spin ladder with new parameters in bridging to real compounds
Zu-Jian Ying, Itzhak Roditi, Huan-Qiang Zhou
We study the field-induced quantum phase transitions (QPT) and the relevant magnetic properties of a spin-1/2 two-leg integrable spin ladder (ISL), of which the system parameters i…
