The interaction of light and matter at the single-photon level is of central importance in
various fields of physics, including, eg, condensed matter physics, astronomy, quantum …

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

We discuss how large amounts of steady-state quantum squeezing (beyond 3 dB) of a
mechanical resonator can be obtained by driving an optomechanical cavity with two control …

We study theoretically a three-mode optomechanical system where two mechanical
oscillators are independently coupled to a single cavity mode. By optimized two-tone or four …

Quantum squeezing in mechanical systems is not only a key signature of macroscopic
quantum effects, but can also be utilized to advance the metrology of weak forces. Here we …

The quantum nonlinear regime of optomechanics is reached when nonlinear effects of the
radiation pressure interaction are observed at the single-photon level. This requires …

We theoretically demonstrate a viable approach to spin squeezing in optical lattice clocks
via optical dressing of one clock state to a highly excited Rydberg state, generating …

The interaction between an atomic ensemble and a light mode in a high-finesse optical
cavity can easily reach the strong-coupling regime, where quantum effects dominate. In this …

We present an experimental study on the nonequilibrium tunnel dynamics of two coupled
one-dimensional Bose-Einstein quasicondensates deep in the Josephson regime …

We propose and analyze an approach for preparation of high fidelity entanglement and
antiferromagnetic states using Rydberg mediated interactions with dissipation. Using …
