We introduce the idea of actually cooling quantum systems by means of incoherent thermal light, hence giving rise to a counterintuitive mechanism of "cooling by heating." In this effect, the mere incoherent occupation of a quantum mechanical mode serves as a trigger to enhance the coupling between other modes. This notion of effectively rendering states more coherent by driving with incoherent thermal quantum noise is applied here to the optomechanical setting, where this effect occurs most…

Antibunching via cooling by heating
We investigate statistics of the photon (phonon) field undergoing linear and nonlinear damping processes. An effective two-photon (phonon) nonlinear “cooling by heating” process is realized from
Coherence-assisted single-shot cooling by quantum absorption refrigerators
The extension of thermodynamics into the quantum regime has received much attention in recent years. A primary objective of current research is to find thermodynamic tasks which can be enhanced by
Ground-state cooling of mechanical resonators by hot thermal light
We propose a scheme to cool down a mechanical resonator to its quantum ground-state, which is interacting with a cavity mode via the optomechanical coupling. As opposed to standard laser cooling
Does “cooling by heating” protect quantum correlations?
TLDR
It is found that at both zero and finite temperature, depending on the parameters used, quantum correlations can be enhanced even when increasing the damping rates, a somewhat counterintuitive result.

A class of Hamiltonians that are experimentally feasible in several contexts within quantum optics and lead to so-called cooling by heating for fermionic as well as for bosonic systems has been

Quantum coherence, many-body correlations, and non-thermal effects for autonomous thermal machines
TLDR
Previous models of autonomous machines are extended to include quantum batteries made of arbitrary systems of discrete spectrum, which allows an efficiency upper bound, called maximal achievable efficiency, to be shown to be always achievable, in contrast with previous upper bounds based only on the Second Law.
Physical Implementations of Quantum Absorption Refrigerators
Absorption refrigerators are autonomous thermal machines that harness the spontaneous flow of heat from a hot bath into the environment in order to perform cooling. Here we discuss quantum
Optical Cooling of Magnons.
TLDR
This work model the cooling of a sphere made of a magnetic insulator, such as yttrium iron garnet, using a monochromatic laser source and predicts that such a cooling process can significantly reduce the temperature of the magnetic order within current technology.
Small quantum absorption refrigerator with reversed couplings.
TLDR
A missing design of a two-qubit fridge is presented, the main feature of which is that one of the two machine qubits is itself maintained at a temperature colder than the cold bath.

Entangled light from white noise.
TLDR
The entanglement is maximized for intermediate values of the cavity damping rates and the intensity of the white noise field, vanishing both for small and for large values of these parameters and thus exhibiting a stochastic-resonancelike behavior.

The observation of self-cooling of a micromirror by radiation pressure inside a high-finesse optical cavity is reported, indicating changes in intensity in a detuned cavity, provide the mechanism for entropy flow from the mirror’s oscillatory motion to the low-entropy cavity field.

TLDR
The observation of optomechanical normal mode splitting is reported, which provides unambiguous evidence for strong coupling of cavity photons to a mechanical resonator, which paves the way towards full quantum optical control of nano- and micromechanical devices.
Gently modulating optomechanical systems.
TLDR
It is found that in a framework of optomechanical systems that are driven with a mildly amplitude-modulated light field, but that are not subject to classical feedback or squeezed input light, large degrees of squeezing of a mechanical micromirror can be achieved without the need of any feedback and control.
