Entropy, non-classical property of the trapped ion system driven by running-wave lasers
Xiang Liu, 方卯发
Abstract
We study the dynamical behaviour of the ionic inversion in a trapped ion system in running-wave lasers,and we discuss the properties of entanglement between the ion and phonons and the statistics of the vibrational phonon field.It is shown that the appearance of the super-revivals of the ion inversion is dependent on the initial parameters of the vibrational phonon field.The Schredinger cat and sub-Poissonican statistics of the phonon field can be also exhibited in this system for suitable initial values.
