Signatures of nonlinear cavity optomechanics in the weak coupling regime.
It is shown that if the strong laser drive is detuned by half the mechanical frequency, optomechanically induced transparency also occurs due to resonant two-photon processes, and this effect provides a new method of measuring the average phonon number of the mechanical oscillator.
Quantum synchronization of a driven self-sustained oscillator.
This work investigates synchronization in the simplest quantum-mechanical scenario possible, i.e., a quantum- mechanical self-sustained oscillator coupled to an external harmonic drive, and shows that there is a steplike crossover to a synchronized state as a function of the driving strength.
Strong mechanical driving of a single electron spin
The efficient and robust manipulation of single spins is an essential requirement for successful quantum devices. The manipulation of a single nitrogen–vacancy spin centre is now demonstrated by…
Cooling and squeezing via quadratic optomechanical coupling
We explore the physics of optomechanical systems in which an optical cavity mode is coupled parametrically to the square of the position of a mechanical oscillator. We derive an effective master…
Topological framework for directional amplification in driven-dissipative cavity arrays
A theoretical framework based on the introduction of a topological invariant that helps to understand non-reciprocity and directional amplification in driven-dissipative cavity arrays is presented.
This study shows that in this limit the power spectrum has multiple sidebands and that the cavity response has several resonances in the resolved-sideband limit, and finds non-Gaussian steady states of the mechanical oscillator when multiphoton transitions are resonant.
Quantum synchronization of two Van der Pol oscillators
Synchronization of two dissipatively coupled Van der Pol oscillators in the quantum regime is studied. Due to quantum noise strict frequency locking is absent and is replaced by a crossover from weak…
Quantum Synchronization Blockade: Energy Quantization Hinders Synchronization of Identical Oscillators.
It is shown that this wisdom fails in the deep quantum regime, where the uncertainty of amplitude narrows down to the level of single quanta, and paves the way for investigations of new quantum synchronization phenomena in oscillator networks both theoretically and experimentally.

The reversed dissipation regime where the mechanical energy relaxation rate exceeds the energy decay rate of the electromagnetic cavity is analyzed and it is demonstrated that this regime allows for mechanically induced amplification (or cooling) of theelectromagnetic mode.

This work proposes and demonstrates a purely optomechanical circulator with reconfigurable transmission without the need for direct coupling between input and output modes and shows how quantum-limited circulators can be realized with the same principle.
