We demonstrate cavity cooling of all motional degrees of freedom of an atomic ensemble using light that is far detuned from the atomic transitions by several gigahertz. The cooling is achieved by cavity-induced frequency-dependent asymmetric enhancement of the atomic emission spectrum, thereby extracting thermal kinetic energy from the atomic system. Within 100 ms, the atomic temperature is reduced from 200 to 10  μK, where the final temperature is mainly limited by the linewidth of the cavity…

Theory of Bose condensation of light via laser cooling of atoms
A Bose-Einstein condensate (BEC) is a quantum phase of matter achieved at low temperatures. Photons, one of the most prominent species of bosons, do not typically condense due to the lack of a
Photon thermalization via laser cooling of atoms
Laser cooling of atomic motion enables a wide variety of technological and scientific explorations using cold atoms. Here we focus on the effect of laser cooling on the photons instead of on the
Feedback induced spin-phonon polaron
We study a hybrid system composed of a three-level atomic ensemble inside an optomechanical cavity. The mechanical oscillator is coupled to the internal state of the atomic ensemble via
Multimode collective scattering of light in free space by a cold atomic gas
We have studied collective recoil lasing by a cold atomic gas, scattering photons from an incident laser into many radiation modes in free space. The model consists of a system of classical equations
Laser cooling with adiabatic transfer on a Raman transition
Sawtooth Wave Adiabatic Passage (SWAP) laser cooling was recently demonstrated using a narrow-linewidth single-photon optical transition in atomic strontium and may prove useful for cooling other
Cavity-Based 3D Cooling of a Levitated Nanoparticle via Coherent Scattering.
TLDR
C cavity cooling of all three translational degrees of motion of a levitated nanoparticle in vacuum is experimentally realized and it is found that the cooling efficiencies depend on the particle position within the intracavity standing wave.
Cavity Cooling of a Levitated Nanosphere by Coherent Scattering.
TLDR
By achieving nanometer-level control over the particle location, this work optimize the position-dependent coupling and demonstrate axial cooling by two orders of magnitude at background pressures of 6×10^{-2}  mbar.
Self-ordering and cavity cooling using a train of ultrashort pulses
A dilute atomic gas in an optical resonator exhibits a phase transition from a homogeneous density to crystalline order when laser illuminated orthogonal to the resonator axis. We study this
One-step engineering many-atom NOON state
We propose a one-step scheme for driving many atoms into a NOON state. In this scheme, two cavities are coupled to each other through the photon-hopping interaction and each cavity contains N
Quantum sensing and cooling in three-dimensional levitated cavity optomechanics
Typical quantum cavity optomechanics allows cooling and detection of a single mechanical degree of freedom with its motion along the cavity axis. However, a recent breakthrough using cavities
