Propagation of coherent light in a Kerr nonlinear medium can be mapped onto a flow of an equivalent fluid. Such an effective fluid possesses many features which allow us to treat it as a special type of quantum liquid. Here we use this mapping to model the conditions in the vicinity of a black hole horizon. To be more specific, a black hole horizon is modeled by means of a Laguerre-Gauss beam....

GINGER (Gyroscopes IN General Relativity) is a proposal aiming at measuring the Lense-Thirring effect with an experiment based on Earth. It is based on an array of ring lasers, which are the most sensitive inertial sensors to measure the rotation rate of the Earth. GINGERINO is a ring laser prototype installed inside the underground laboratory of Gran Sasso. We describe the preliminary...

When the two-body scattering length $a$ of two identical bosons
diverges the three-boson spectrum shows the Efimov effect.
In this limit, the unitary limit, an infinite set of bound states,
$E_3^n$, appears approaching zero in a geometrical progression. In
other words, the $L=0$ sector of three identical bosons presents
a discrete scaling invariance (DSI). As the absolute value of $a$...

The recent observation of gravitational waves from merging black holes (BH) opens up the possibility of exploring the theory of gravity at an unprecedented level.
It is therefore important to understand if and which modifications of General Relativity (GR) could be observed. I will show how the most convenient approach to address this question is to resort to a maximally model-independent,...

In two-dimensional superfluids quantized vortices play a key role in
determining finite-temperature properties, as the superfluid phase and the normal state are separated by a vortex unbinding transition,
the Berezinskii-Kosterlitz-Thouless transition. Very recent experiments with two-dimensional superfluid fermions [1] motivate the present work: we present theoretical results [2] based on...
