We propose an experimental scheme for the measurement of entanglement between two two-level atoms. Our scheme requires one of the two entangled atoms to interact with a cavity field dispersively, and we show that by measuring the zero time-delay seco

This theoretical work initiates contact between two frontier disciplines of physics, namely, atomic superfluid rotation and cavity optomechanics. It considers an annular Bose-Einstein condensate, which exhibits dissipationless flow and is a paradigm

Phonon lasers are mechanical analogues of the ubiquitous optical laser and have been realized in a variety of contexts1–12. However, no such demonstration exists for mesoscopic levitated optomechanical systems, which are emerging as important platf

We present theoretical and experimental investigations of higher order correlations of mechanical motion in the recently demonstrated optical tweezer phonon laser, consisting of a silica nanosphere trapped in vacuum by a tightly focused optical beam

We demonstrate that the conservation of extremal ellipticity for an astigmatic Gaussian beam propagating in a rotationally invariant medium, for example, an arbitrary sequence of free space propagation and stigmatic lenses, initially identified by Lo

We theoretically describe a levitated Mie particle phonon laser, obtained by coupling the particle oscillations to a whispering gallery mode via laser radiation. We show that ultrasensitive force sensing can be performed using this platform.

We theoretically explore a quantum memory using a single nanoparticle levitated in an optical dipole trap and subjected to feedback cooling. This protocol is realized by storing and retrieving a single-photon quantum state from a mechanical mode in l

We propose a method to generate transiently nonclassical motional states in a levitated optomechanical system. The nonclassicality arises from a nonlinearity induced by coupling the mechanical motion of a nanodiamond carrying a nitrogen-vacancy cente

Hollow-core photonic crystal fibers offer a versatile platform for developing cutting edge optical sensors through particle levitation. Here, the orbital angular momentum mode of such a fiber is utilized to rotate a dielectric nanoparticle, levitated
