Optical trap** is the craft of manipulating objects with light. Decades after its first inception
in 1970, the technique has become a powerful tool for ultracold‐atom physics and …

In the last decade, two-dimensional organic single crystals (2D OSCs), defined as a class of
ultrathin crystals with atomic or molecular level thickness and micrometer-scale-lateral …

A photon avalanche (PA) effect that occurs in lanthanide-doped solids gives rise to a giant
nonlinear response in the luminescence intensity to the excitation light intensity. As a result …

Avalanche phenomena use steeply nonlinear dynamics to generate disproportionately large
responses from small perturbations, and are found in a multitude of events and materials …

An ensemble of emitters can behave very differently from its individual constituents when
they interact coherently via a common light field. After excitation of such an ensemble …

The permutational invariance of identical two-level systems allows for an exponential
reduction in the computational resources required to study the Lindblad dynamics of …

Ordered atomic arrays with subwavelength lattice spacing emit light collectively. For fully
inverted atomic arrays, this results in an initial burst of radiation and a fast buildup of …

We show that induced dipole-dipole interactions allow for photon blockade in
subwavelength ensembles of two-level, ground-state neutral atoms. Our protocol relies on …

We study the impact of cooperative many-body effects on the operation of periodically-driven
quantum thermal machines, particularly heat engines and refrigerators. In suitable …

We study the all-to-all connected XYZ (anisotropic-Heisenberg) spin model with local and
collective dissipations, comparing the results of mean-field (MF) theory with the solution of …
