Large-N scaling behavior of the ground-state energy and fidelity in the Dicke Model
Tao Liu, Yu-Yu Zhang, Qing-Hu Chen +1
Within the numerically exact solution to the Dicke model proposed previously, we study the quantum criticality in terms of the ground-state (GS) energy, fidelity, and the order par…

Accurate numerical solution to the finite-size Dicke model
Qing-Hu Chen, Yu-Yu Zhang, Tao Liu +1
By using extended bosonic coherent states, a new technique to solve the Dicke model exactly is proposed in the numerical sense. The accessible system size is two orders of magnitud…
