Analogue gravity is a research programme which investigates analogues of general
relativistic gravitational fields within other physical systems, typically but not exclusively …

Hawking argued that black holes emit thermal radiation via a quantum spontaneous
emission. To address this issue experimentally, we utilize the analogy between the …

Event horizons of astrophysical black holes and gravitational analogues have been
predicted to excite the quantum vacuum and give rise to the emission of quanta, known as …

We measured the power spectrum and two-point correlation function for the randomly
fluctuating free surface on the downstream side of a stationary flow with a maximum Froude …

We show that the well-known Čerenkov effect contains new phenomena arising from the
quantum nature of charged particles. The Čerenkov transition amplitudes allow coupling …

Time-varying optical media, whose dielectric properties are actively modulated in time,
introduce a host of novel effects in the classical propagation of light, and are of intense …

Hawking radiation, despite being known to theoretical physics for nearly 40 years, remains
elusive and undetected. It also suffers, in its original context of gravitational black holes, from …

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

Sources of photons with controllable quantum properties such as entanglement and
squeezing are desired for applications in quantum information, metrology and sensing …
