Imposing chirality on a physical system engenders unconventional energy flow and
responses, such as the Aharonov–Bohm effect and the topological quantum Hall phase for …

Typical quantum cavity optomechanics allows cooling and detection of a single mechanical
degree of freedom with its motion along the cavity axis. However, a recent breakthrough …

A time-dependent periodical field can be utilized to efficiently modify the Rabi coupling of
system, exhibiting nontrivial dynamics. We propose a scheme to show that this feature can …

We investigate theoretically the nonlinear effects in a Floquet-driven optomechanical system
with quadratic coupling. When the periodically modulated driving field is strong, we establish …

The radiation-pressure interaction between one or more laser fields and a mechanical
oscillator gives rise to a wide range of phenomena: From sideband cooling and backaction …

Cavity optomechanics and electromechanics form an established field of research
investigating the interactions between electromagnetic fields and the motion of quantum …

Open quantum systems can display periodic dynamics at the classical level either due to
external periodic modulations or to self-pulsing phenomena typically following a Hopf …

We study quantum noise in a nonequilibrium, periodically driven, open system attached to
static leads. Using a Floquet Green's function formalism we show, both analytically and …

Asymmetry in the motional sideband spectrum is a signature of the quantum regime of
mechanical oscillators. It enables self-calibrated thermometry measurements, and has …

Part I of this thesis is concerned with cavity optomechanical systems subject to periodic
driving. We develop a Floquet approach to solve time-periodic quantum Langevin equations …
