Abstract: We analytically and numerically investigate quadrature squeezing in an extended two-site Bose–Hubbard model with pair tunneling by using the rotating-wave approximation. It is shown that single particle tunneling and the density-dependent tunneling have no influence… read more here.

Abstract: We consider a quantum many-body system-the Bose-Hubbard system on three sites-which has a classical limit, and which is neither strongly chaotic nor integrable but rather shows a mixture of the two types of behavior. We… read more here.
