Quantum heat engines are modeled by thermodynamic cycles with quantum-mechanical
working media. Since high engine efficiencies require adiabaticity, a major challenge is to …

Quadratic light-matter interactions are nonlinear couplings such that quantum emitters
interact with photonic or phononic modes exclusively via the exchange of excitation pairs …

We study the performance of quantum Stirling machines based on two Heisenberg-coupled
spins as the working system near quantum critical point (QCP). During the heat cycle, the …

Entangled photon pairs have been used for molecular spectroscopy in the form of entangled
two-photon absorption and in quantum interferometry for precise measurements of light …
