We provide a full quantum description of the optomechanical system formed by a Fabry-P\'erot cavity with a movable micromechanical mirror whose center-of-mass and internal elastic modes are coupled to the driven cavity mode by both radiation pressure and photothermal force. Adopting a quantum Langevin description, we investigate simultaneous cooling of the micromirror elastic and center-of-mass modes, and also the entanglement properties of the optomechanical multipartite system in its steady…

Photothermally induced transparency in coupled-cavity system
We aim to study the properties of the output probe field (OPF) in a system composed of two coupled-optical cavities. A strong pump and a weak probe field drives the left cavity whereas the right-side

Photothermally induced transparency
TLDR
This work introduces the concept of photothermally induced transparency (PTIT), which can suppress the coupling between an optical resonator and a traveling optical field and shows that the dispersion of the resonator can be modified to exhibit slow or fast light.
Multimode laser cooling and ultra-high sensitivity force sensing with nanowires.
TLDR
This work shows broadband multimode cooling of -23 dB down to a temperature of 8 ± 1 K in the stationary regime through the use of periodic quiescence feedback cooling, and shows improved signal-to-noise ratios for the measurement of transient signals.

Quantum theory of cavity-assisted sideband cooling of mechanical motion.
TLDR
It is found that reaching the quantum limit of arbitrarily small phonon numbers requires going into the good-cavity (resolved phonon sideband) regime where the cavity linewidth is much smaller than the mechanical frequency and the corresponding cavity detuning.
