Abstract
In this paper we propose an efficient method for creating macroscopically distinct mechanical superposition states in an ultra strongly-coupled light-matter system. By modulating the opto-mechanical coupling sinusoidally, the radiation pressure can be turned into a built-in resonant driving force effectively. Thus the mechanical displacement can be significantly amplified.
