Recent years have witnessed an explosion of interest in quantum devices for the production,
storage, and transfer of energy. This Colloquium concentrates on the field of quantum …

The rate at which matter emits or absorbs light can be modified by its environment, as
markedly exemplified by the widely studied phenomenon of superradiance. The reverse …

Performance of nano-and microscale heat engines can be improved with the help of
quantum-mechanical phenomena. Recently, heat reservoirs with quantum coherence have …

We propose a quantum-enhanced heat engine with entanglement. The key feature of our
scheme is superabsorption, which facilitates enhanced energy absorption by entangled …

Photon-mediated interactions within an excited ensemble of emitters can result in Dicke
superradiance, where the emission rate is greatly enhanced, manifesting as a high-intensity …

We propose charging protocols for quantum batteries based on quantum superpositions of
trajectories. Specifically, we consider that a qubit (the battery) interacts with multiple cavities …

Cooperative effects of multiple quantum emitters are characterized by transitions via
delocalized collective states with altered emission properties due to the existence of …

We show that the lower levels of a large-spin network with a collective antiferromagnetic
interaction and collective couplings to three reservoirs may function as a quantum …

Indistinguishable quantum emitters confined to length scales smaller than the wavelength of
the light become superradiant. Compared to uncorrelated and distinguishable emitters …

Over the last few decades, nonlinear optics has become significantly more nonlinear,
traversing nearly a billionfold improvement in energy efficiency, with ultrafast nonlinear …
