Title: A new double-pass type of the optical spring
Authors: F. Ya. Khalili,
Abstract summary: In detuned optical cavities, the radiation pressure force acting on the mirrors depends on their displacements. We consider a new type of the optical spring that does not require the cavity. We propose two possible implementation of this concept, suitable, respectively, for the atomic spin ensembles and for the laser gravitational-wave detectors.

Abstract: In detuned optical cavities, the radiation pressure force acting on the mirrors depends on their displacements. This is equivalent to the rigidity (the optical spring), inserted between the mirrors. This effect can be used for optimization of the mechanical susceptibility of probe mirrors in high-precision force sensors. However, in some cases, the use of detuned cavities or even just any high-finesse cavities could be problematic due to technological constraints. We consider a new type of the optical spring that does not require the cavity (but can use a resonance tuned one to increase the optomechanical coupling). Instead, it uses the double interaction of the probing light with the mechanical object. We propose two possible implementation of this concept, suitable, respectively, for the atomic spin ensembles and for the laser gravitational-wave detectors.

Broadband Multidimensional Variational Measurement with Non-Symmetric Coupling [41.94295877935867]
We analyze a general case of the non-symmetric measurement scheme, in which the coupling strengths with the light modes are not equal to each other. We found that the back action can be completely excluded from the measurement result in the case of the asymmetric system.

Dissipative and dispersive cavity optomechanics with a frequency-dependent mirror [0.0]
microcavity-based optomechanical systems are placed in the unresolved-sideband regime, preventing sideband-based ground-state cooling. We analyze such an optomechanical system, whereby one of the mirrors is strongly frequency-dependent, i.e., a suspended Fano mirror. We formulate a quantum-coupled-mode description that includes both the standard dispersive optomechanical coupling as well as dissipative coupling.

We study two cavities separated by a vibrating two-sided perfect mirror and show that, within currently available experimental parameters, this system displays photon-pair hopping. In particular, the two-photon hopping is not due to tunneling, but rather to higher order resonant processes.

High-Frequency Gravitational-Wave Detection Using a Chiral Resonant Mechanical Element and a Short Unstable Optical Cavity [59.66860395002946]
We suggest the measurement of the twist of a chiral mechanical element induced by a gravitational wave. The induced twist rotates a flat optical mirror on top of this chiral element, leading to the deflection of an incident laser beam. We estimate a gravitational wave strain sensitivity between 10-21/sqrtHz and 10-23/sqrtHz at around 10 kHz frequency.
