Optomechanical systems with linear and quadratic position couplings: Dynamics and optimal estimation
Yaqing Xy Wang, Claudio Sanavio, József Zsolt Bernád
We study the dynamics of an optomechanical system consisting of a single-mode optical field coupled to a mechanical oscillator, where the nonlinear interaction includes both linear…
Estimation of disorders in the rest positions of two membranes in optomechanical systems
Claudio Sanavio, József Zsolt Bernád, André Xuereb
The formalism of quantum estimation theory is applied to estimate the disorders in the positions of two membranes positioned in a driven cavity. We consider the coupled-cavities an…
Nonreciprocal topological phononics in optomechanical arrays
Claudio Sanavio, Vittorio Peano, André Xuereb
We propose a platform for robust and tunable nonreciprocal phonon transport based on arrays of optomechanical microtoroids. In our approach, time-reversal symmetry is broken by the…
Fisher-information-based estimation of optomechanical coupling strengths
Claudio Sanavio, József Zsolt Bernád, André Xuereb
The formalism of quantum estimation theory, focusing on the quantum and classical Fisher information, is applied to the estimation of the coupling strength in an optomechanical sys…
Optimal estimation of matter-field coupling strength in the dipole approximation
József Zsolt Bernád, Claudio Sanavio, André Xuereb
This paper is devoted to the study of the Bayesian-inference approach in the context of estimating the dipole coupling strength in matter-field interactions. In particular, we cons…
Optimal estimation of the optomechanical coupling strength
József Zsolt Bernád, Claudio Sanavio, André Xuereb
We apply the formalism of quantum estimation theory to obtain information about the value of the nonlinear optomechanical coupling strength. In particular, we discuss the minimum m…
