The dissipative properties of an optical cavity can be effectively controlled by placing it in a feedback loop where the light at the cavity output is detected and the corresponding signal is used to modulate the amplitude of a laser field which drives the cavity itself. Here we show that this effect can be exploited to improve the performance of an optomechanical heat engine which makes use of polariton excitations as working fluid. In particular we demonstrate that, by employing a positive…

Optomechanics for quantum technologies
The ability to control the motion of mechanical systems through interaction with light has opened the door to a plethora of applications in fundamental and applied physics. With experiments routinely
Feedback-enabled microwave quantum illumination
A simple feedback scheme can be used to operate efficiently a microwave-quantum-illumination device based on electro-optomechanical systems also in regimes in which excess dissipation would,
Macroscopic Schrödinger cat state swapping in optomechanical system.
Numerical and analytical results show that this approach can be used to reduce the effects of decoherence, which suggests that the state swapping proposal is effective and feasible.
Nonequilibrium Many-Body Quantum Engine Driven by Time-Translation Symmetry Breaking.
This work investigates the impact of collective effects on quantum engines that extract mechanical work from a many-body system out of equilibrium using an optomechanical cavity setup with an interacting atomic gas as a working fluid and finds that such engines produce work under periodic driving.
Quantum thermodynamic devices: From theoretical proposals to experimental reality
Thermodynamics originated in the need to understand novel technologies developed by the Industrial Revolution. However, over the centuries, the description of engines, refrigerators, thermal

Enhancement of three-mode optomechanical interaction by feedback-controlled light
We realise a feedback-controlled optical Fabry-Perot cavity in which the transmitted cavity output is used to modulate the input amplitude fluctuations. The resulting phase-dependent fluctuations of
Enhancing Sideband Cooling by Feedback-Controlled Light.
We realize a phase-sensitive closed-loop control scheme to engineer the fluctuations of the pump field which drives an optomechanical system and show that the corresponding cooling dynamics can be
Cavity optomechanics with feedback-controlled in-loop light
It has recently been shown [Rossi et al., Phys. Rev. Lett. 119, 123603 (2017); ibid. 120, 073601 (2018)] that feedback--controlled in--loop light can be used to enhance the efficiency of
Quantum optomechanical heat engine.
The basic properties of the system are discussed in two different regimes: in the optical domain it is possible to extract work from the thermal energy of a mechanical resonator at finite temperature, while in the microwave range one can in principle exploit the cycle to extractWork from the blackbody radiation background coupled to an ultracold atomic ensemble.
Suppression of Stokes scattering and improved optomechanical cooling with squeezed light
We develop a theory of optomechanical cooling with a squeezed input light field. We show that Stokes heating transitions can be \emph{fully} suppressed when the driving field is squeezed below the

We propose a realization of a quantum heat engine in a hybrid microwave-optomechanical system that is the analog of a classical straight-twin engine. It exploits a pair of polariton modes that
Work extraction from heat-powered quantized optomechanical setups
In contrast to laser-powered self-induced oscillations, work extraction from a broadband heat bath does not require coherence or phase-locking: an initial phase-averaged coherent state of the oscillator still yields work, as opposed to an initial Fock-state.

It is shown how a levitated nanoparticle in an optical trap inside a cavity can be used to realize a Stirling cycle in the underdamped regime and develops a systematic optimization procedure to determine optimal driving protocols.
