Abstract
Optomechanical systems serve as a versatile platform for the study of classical and quantum phenomena both in the
mesoscopic and macroscopic regime. They are also useful to analyze higher-order nonlinear effects or control the
transmission, storage and retrieval of optical signals. Moreover, by integrating such systems into solid-state platforms
and coupling other degrees of freedom to the optical and mechanical modes, one can study a multitude of
phenomena arising in hybrid systems. In this thesis, we theoretically explore a handful of such classical and quantum
phenomena that emerge due to the radiation-pressure-induced optomechanical interaction in different configurations
of hybrid open quantum systems. Specifically, we analyze (i) the behavior of quantum synchronization in opticallycoupled
optomechanical systems, (ii) the transmission of a weak probe beam in an optomechanical analogue of
annularly-trapped Bose-Einstein condensate placed inside a cavity, and (iii) the generation and the enhancement of
entanglement and mechanical squeezing in modulated optomechanical setups. Our studies may find applications in
optical sensing, quantum communication and quantum information processing with continuous variables.
