Photothermal optomechanics in superfluid helium coupled to a fiber-based cavity
A. D. Kashkanova, A. B. Shkarin, C. D. Brown +7
Presented in this paper are measurements of an optomechanical device in which various acoustic modes of a sample of superfluid helium couple to a fiber-based optical cavity. In con…
Millimeter-long Fiber Fabry-Perot cavities
Konstantin Ott, Sebastien Garcia, Ralf Kohlhaas +4
We demonstrate fiber Fabry-Perot (FFP) cavities with concave mirrors that can be operated at cavity lengths as large as 1.5mm without significant deterioration of the finesse. This…
Superfluid Brillouin Optomechanics
A. D. Kashkanova, A. B. Shkarin, C. D. Brown +7
Optomechanical systems couple an electromagnetic cavity to a mechanical resonator which is typically formed from a solid object. The range of phenomena accessible to these systems…
Deterministic generation of multiparticle entanglement by quantum Zeno dynamics
Giovanni Barontini, Leander Hohmann, Florian Haas +2
Multiparticle entangled quantum states, a key resource in quantum-enhanced metrology and computing, are usually generated by coherent operations exclusively. However, unusual forms…
