A bstract We compute the production rate of the energy density carried by gravitational
waves emitted by a Standard Model plasma in thermal equilibrium, consistently to leading …

The creation of delocalized coherent superpositions of quantum systems experiencing
different relativistic effects is an important milestone in future research at the interface of …

A dispersionless shock wave in a fluid without friction develops an acoustic spacetime
singularity which is naked (not hidden by a horizon). We show that this naked nondispersive …

An interesting proposal for detecting gravitational waves involves quantum metrology of
Bose–Einstein condensates (BECs). We consider a forced modulation of the speed of sound …

The dynamics of sound in a fluid is intrinsically nonlinear. We derive the consequences of
this fact for the analogue gravitational field experienced by sound waves, by first describing …

We propose an experiment based on a Bose–Einstein condensate interferometer for
strongly constraining fifth-force models. Additional scalar fields from modified gravity or …

Additional scalar fields from scalar-tensor, modified gravity or higher dimensional theories
beyond general relativity may account for dark energy and the accelerating expansion of the …

We introduce a quantum interferometric scheme that uses states that are sharp in frequency
and delocalized in position. The states are frequency modes of a quantum field that is …

We develop a method for computing the Bogoliubov transformation experienced by a
confined quantum scalar field in a globally hyperbolic spacetime, due to the changes in the …

In the present Master's thesis, I describe the research I conducted during my Master's
program on the topic of analogue gravity. This line of research was initiated by Bill Unruh …
