The study of spinning systems plays a question of interest in several research branches in
physics. It allows the understanding of simple classical mechanical systems but also …

The amplification of radiation by superradiance is a universal phenomenon observed in
numerous physical systems. We demonstrate that superradiant scattering generates …

It was recently found that the optical field fluctuations in self-defocusing media can be
described by sound waves propagating in a two-dimensional photon fluid. This photon fluid …

The control over the geometry and topology of quantum systems is crucial for advancing
novel quantum technologies. This work provides a synthesis of recent insights into the …

The production of quantum field excitations or particles in cosmological spacetimes is a
hallmark prediction of curved quantum field theory. The generation of cosmological …

In this work, we study the inverse problem of analog gravity systems which admit rotation
and energy-dependent boundary conditions. By extending two recent results, we provide a …

Pair creation is a fundamental prediction of quantum field theory in curved spacetimes.
While classical aspects of this phenomenon have been observed, the experimental …

Optical solitons classically are stationary solutions of the nonlinear Schrödinger equation.
We perform a quantum field theoretic treatment by quantising a linearised fluctuation field …

An accelerated observer moving through empty space sees particles appearing and
disappearing, while an observer with a constant velocity does not register any particles. This …

Black holes (BH) are challenging as objects of study and measurement. The extreme
conditions they produce make direct observation a formidable task. Here we provide an …
