Advances in quantum technologies are giving rise to a revolution in the way fundamental
physics questions are explored at the empirical level. At the same time, they are the seeds …

Investigating and verifying the connections between the foundations of quantum mechanics
and general relativity will require extremely sensitive quantum experiments. To provide …

A compact detector for space-time metric and curvature is highly desirable. Here we show
that quantum spatial superpositions of mesoscopic objects could be exploited to create such …

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 …

A description of the dynamical response of uniformly trapped Bose–Einstein condensates
(BECs) to oscillating external gravitationalfields is developed, with the inclusion of dam** …

We study possibilities of creation and detection of oscillating gravitational fields from lab-
scale high energy, relativistic sources. The sources considered are high energy laser beams …

Some aspects of atom-field interactions in curved spacetime are reviewed. Of great interest
are quantum radiative and entanglement processes arising out of Rindler and black hole …

Light propagation in curved spacetime is at the basis of some of the most stringent tests of
Einstein's general relativity. At the same time, light propagation in media is at the basis of …

Whether the cosmological expansion can influence the local dynamics, below the galaxy
clusters scale, has been the subject of intense investigations in the past three decades. In …

We study the time evolution of two coupled quantum harmonic oscillators interacting through
nonlinear optomechanical-like Hamiltonians that include cross-Kerr interactions. We employ …
