DISSIPATIVE DYNAMICS OF A SINGLE PARTICLE IN AN ION TRAP
Chi‐Fai Lo, David Kiang
Abstract
In this paper we have investigated the time evolution of a dissipative quantum time-dependent oscillator which can be used to model particle trapping in an ion trap. Our analysis shows that the nonadiabatic changes in the oscillator mass and/or frequency as well as the dissipation constitute two competing forces on the squeezing properties of the system — the former helps generate the squeezing effect whereas the latter tries to destroy it.
