Measurement of Penrose superradiance in a photon superfluid
Maria Chiara Braidotti, Radivoje Prizia, Calum Maitland +6
The superradiant amplification in the scattering from a rotating medium was first elucidated by Sir Roger Penrose over 50 years ago as a means by which particles could gain energy…
Superradiant scattering in fluids of light
Angus Prain, Calum Maitland, Daniele Faccio +1
We theoretically investigate the scattering process of Bogoliubov excitations on a rotating photon-fluid. Using the language of Noether currents we demonstrate the occurrence of a…
Optical Analogue of the Dynamical Casimir Effect in a Dispersion-Oscillating Fibre
Stefano Vezzoli, Arnaud Mussot, Niclas Westerberg +6
The dynamical Casimir effect is the generation of pairs of real particles or photons from the vacuum as a result of a non-adiabatic change of a system parameter or boundary conditi…
Vacuum radiation and frequency-mixing in linear light-matter systems
Niclas Westerberg, Angus Prain, Daniele Faccio +1
Recent progress in photonics has led to a renewed interest in time-varying media that change on timescales comparable to the optical wave oscillation time. However, these studies t…
Rotating black hole geometries in a two-dimensional photon superfluid
David Vocke, Calum Maitland, Angus Prain +4
Analogue gravity studies the physics of curved spacetime in laboratory experiments, where the propagation of elementary excitations in inhomogeneous flows is mapped to those of sca…
Spontaneous photon production in time-dependent epsilon-near-zero materials
A. Prain, S. Vezzoli, N. Westerberg +2
Quantum field theory predicts that a spatially homogeneous but temporally varying medium will excite photon pairs out of the vacuum state. However, this important theoretical predi…
