Ponderomotive control of quantum macroscopic coherence 论文

摘要

It is shown that because of the radiation pressure a Schr\"odinger cat state can be generated in a resonator with an oscillating wall. The optomechanical control of quantum macroscopic coherence and its detection is taken into account by introducing new cat states. The effects due to the environmental couplings with this nonlinear system are considered by developing an operator perturbation procedure to solve the master equation for the field mode density operator.
