Autonomous feedback stabilization of a cavity-coupled spin oscillator
Julian Wolf, Olive H. Eilbott, Josh A. Isaacs +3
We report out-of-equilibrium stabilization of the collective spin of an atomic ensemble through autonomous feedback by a driven optical cavity. For a magnetic field applied at an a…
Tracking evaporative cooling of a mesoscopic atomic quantum gas in real time
Johannes Zeiher, Julian Wolf, Joshua A. Isaacs +2
The fluctuations in thermodynamic and transport properties in many-body systems gain importance as the number of constituent particles is reduced. Ultracold atomic gases provide a…
Simultaneous retrodiction of multi-mode optomechanical systems using matched filters
Jonathan Kohler, Justin A. Gerber, Emma Deist +1
Generation and manipulation of many-body entangled states is of considerable interest, for applications in quantum simulation or sensing, for example. Measurement and verification…
Negative-mass instability of the spin and motion of an atomic gas driven by optical cavity backaction
Jonathan Kohler, Justin A. Gerber, Emma Dowd +1
We realize a spin-orbit interaction between the collective spin precession and center-of-mass motion of a trapped ultracold atomic gas, mediated by spin- and position-dependent dis…
Cavity-assisted measurement and coherent control of collective atomic spin oscillators
Jonathan Kohler, Nicolas Spethmann, Sydney Schreppler +1
We demonstrate continuous measurement and coherent control of the collective spin of an atomic ensemble undergoing Larmor precession in a high-finesse optical cavity. The coupling…
Complex Squeezing and Force Measurement Beyond the Standard Quantum Limit
L. F. Buchmann, S. Schreppler, J. Kohler +2
A continuous quantum field, such as a propagating beam of light, may be characterized by a squeezing spectrum that is inhomogeneous in frequency. We point out that homodyne detecto…
Cavity-mediated coupling of mechanical oscillators limited by quantum backaction
Nicolas Spethmann, Jonathan Kohler, Sydney Schreppler +2
A complex quantum system can be constructed by coupling simple quantum elements to one another. For example, trapped-ion or superconducting quantum bits may be coupled by Coulomb i…
