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…

Quantum phase transition in the one-dimensional period-two and uniform compass model
Ke-Wei Sun, Yu-Yu Zhang, Qing-Hu Chen
Quantum phase transition in the one-dimensional period-two and uniform quantum compass model are studied by using the pseudo-spin transformation method and the trace map method. Th…
