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…

Lower ground state due to counter-rotating wave interaction in trapped ion system
T. Liu, K. L. Wang, M. Feng
We consider a single ion confined in a trap under radiation of two traveling waves of lasers. In the strong-excitation regime and without the restriction of Lamb-Dicke limit, the H…
