Optimal estimation of time-dependent gravitational fields with quantum optomechanical systems
Sofia Qvarfort, A. Douglas K. Plato, David Edward Bruschi +4
We study the fundamental sensitivity that can be achieved with an ideal optomechanical system in the nonlinear regime for measurements of time-dependent gravitational fields. Using…
Optimal estimation with quantum optomechanical systems in the nonlinear regime
Fabienne Schneiter, Sofia Qvarfort, Alessio Serafini +4
We study the fundamental bounds on precision measurements of parameters contained in a time-dependent nonlinear optomechanical Hamiltonian, which includes the nonlinear light-matte…
Rotation of polarization in the gravitational field of a laser beam - Faraday effect and optical activity
Fabienne Schneiter, Dennis Rätzel, Daniel Braun
We investigate the rotation of the polarization of a light ray propagating in the gravitational field of a circularly polarized laser beam. The rotation consists of a reciprocal pa…
The gravitational field of a laser beam beyond the short wavelength approximation
Fabienne Schneiter, Dennis Rätzel, Daniel Braun
Light carries energy, and therefore, it is the source of a gravitational field. The gravitational field of a beam of light in the short wavelength approximation has been studied by…
