We report a spin-orbit-coupling-induced backaction cooling in an optomechanical system, composed of a spin-orbit-coupled Bose-Einstein condensate trapped in an optical cavity with one movable end mirror, by suppressing heating effects of quantum noises. The collective density excitations of the spin-orbit-coupling-mediated hyperfine states---serving as atomic oscillators equally coupled to the cavity field---trigger strongly driven atomic backaction. We find that the backaction not only revamps…

Dynamical Spin-Orbit Coupling of a Quantum Gas.
Dynamical SOC in quantum gas cavity QED, and the extension to dynamical gauge fields, may enable the creation of Meissner-like effects, topological superfluids, and exotic quantum Hall states in coupled light-matter systems.
Dynamical phase transition of two-component Bose–Einstein condensate with nonlinear tunneling in an optomechanical cavity-mediated double-well system
We investigate the dynamical phase transition of two-component Bose-Einstein condensate with nonlinear tunneling, which is trapped inside a double-well and dispersively coupled to a single mode of a
Dynamic Cooling of a Micromechanical Membrane in a Double-cavity Optomechanical System
We theoretically present an optomechanical cooling scheme of a double optical modes which are coupled with the same mechanical resonator by the radiation pressure to analyze the dynamical cooling of
Holding and transferring matter-wave solitons against gravity by spin–orbit-coupling tweezers
We consider possibilities to grasp and drag one-dimensional solitons in two-component Bose- Einstein condensates (BECs), under the action of gravity, by tweezers induced by spatially confined
Coupling mechanical motion of a single atom to a micromechanical cantilever
We design and analyze a hybrid optomechanical setup to achieve an effective coupling between the mechanical motions of a micromechanical cantilever and a single atom trapped inside a cavity, which is


A new language, Opt, is proposed for writing these objective functions over image- or graph-structured unknowns concisely and at a high level and automatically transforms these specifications into state-of-the-art GPU solvers based on Gauss-Newton or Levenberg-Marquardt methods.
