Emergent phases and novel critical behavior in a non-Markovian open quantum system
H. F. H. Cheung, Y. S. Patil, M. Vengalattore
Open quantum systems exhibit a range of novel out-of-equilibrium behavior due to the interplay between coherent quantum dynamics and dissipation. Of particular interest in these sy…
Atom-based coherent quantum-noise cancellation in optomechanics
F. Bariani, H. Seok, S. Singh +2
We analyze a quantum force sensor that uses coherent quantum noise cancellation (CQNC) to beat the Standard Quantum Limit (SQL). This sensor, which allows for the continuous, broad…
Multimode phononic correlations in a nondegenerate parametric amplifier
S. Chakram, Y. S. Patil, M. Vengalattore
We describe the realization of multimode phononic correlations that arise from nonlinear interactions in a mechanical nondegenerate parametric amplifier. The nature of these correl…
Quantum back-action in spinor condensate magnetometry
S. K. Steinke, S. Singh, P. Meystre +2
We provide a theoretical treatment of the quantum backaction of Larmor frequency measurements on a spinor Bose-Einstein condensate by an off-resonant light field. Two main results…
Quantum measurement backaction from a BEC coupled to a mechanical oscillator
S. K. Steinke, S. Singh, M. E. Tasgin +3
We study theoretically the dynamics of a a hybrid optomechanical system consisting of a macroscopic mechanical membrane magnetically coupled to a spinor Bose-Einstein condensate vi…
Amplification of Fluctuations in a Spinor Bose Einstein Condensate
S. R. Leslie, J. Guzman, M. Vengalattore +3
Dynamical instabilities due to spin-mixing collisions in a Rb F=1 spinor Bose-Einstein condensate are used as an amplifier of quantum spin fluctuations. We demonstrate the s…
