Abstract The study of Bose–Einstein condensation effects in photonic systems has revealed
a rich phenomenology related to spontaneous coherence generation in driven-dissipative …

Technological advances in controlling and manipulating fluids have enabled the
experimental realization of acoustic analogues of gravitational black holes. A flowing fluid …

In most cosmological models, rapid expansion of space marks the first moments of the
Universe and leads to the amplification of quantum fluctuations. The description of …

The traditional view from particle physics is that quantum gravity effects should only become
detectable at extremely high energies and small length scales. Due to the significant …

Nonlinear optics has been a very dynamic field of research with spectacular phenomena
discovered mainly after the invention of lasers. The combination of high intensity fields with …

In this study, we investigate the influence of Hawking decoherence on the quantum
correlations of Dirac fields between Alice and Bob. Initially, they share a Gisin state near the …

We report on the observation of a prethermal state in a nonequilibrium, two-dimensional
fluid of light. Direct measurements of the first order coherence function of the fluid reveal the …

The black-hole laser (BHL) effect is the self-amplification of Hawking radiation in the
presence of a pair of horizons which act as a resonant cavity. In a flowing atomic …

Abstract Reasoning by analogies permeates theoretical developments in physics and
astrophysics, motivated by the unreachable nature of many phenomena at play. For …

We provide a reinterpretation of the quantum vacuum ambiguities that one encounters when
studying particle creation phenomena due to an external and time-dependent agent. We …
