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…
Stationary States and Instabilities of a Mobius Fibre Resonator
Calum Maitland, Matteo Conforti, Arnaud Mussot +1
We examine the steady state and dynamic behaviour of an optical resonator comprised of two interlinked fibre loops sharing a common pump. A coupled Ikeda map models with great accu…
Angular Momentum Supercontinuum from Fibre Rings
Calum Maitland, Fabio Biancalana
Broadband, coherent light carrying optical angular momentum is of potential utility for a variety of classical and quantum communication applications, but at present few such sourc…
Polarisation and Transparency of Relativistically Rotating Two-Level Atoms
Calum Maitland, Matteo Clerici, Fabio Biancalana
Electromagnetism and light-matter interaction in rotating systems is a rich area of ongoing research. We study the interaction of light with a gas of non-interacting two-level atom…
How fast is a twisted photon?
Thomas Roger, Ashley Lyons, Niclas Westerberg +5
Recent measurements have highlighted that spatially shaped photons travel slower than c, the speed of monochromatic, plane waves in vacuum. Here we investigate the intrinsic delay…
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…
