Optical analogues of the Newton-Schrödinger equation and boson star evolution
Thomas Roger, Calum Maitland, Kali Wilson +4
Many gravitational phenomena that lie at the core of our understanding of the Universe have not yet been directly observed. An example in this sense is the boson star that has been…
Quantum Soliton Evaporation
Leone Di Mauro Villari, Ewan M. Wright, Fabio Biancalana +1
We have very little experience of the quantum dynamics of the ubiquitous nonlinear waves. Observed phenomena in high energy physics are perturbations to linear waves, and classical…
Controlling hybrid nonlinearities in transparent conducting oxides via two-colour excitation
M. Clerici, N. Kinsey, C. DeVault +8
Nanophotonics and metamaterials have revolutionised the way we think about optical space (epsilon, mu), enabling us to engineer the refractive index almost at will, to confine ligh…
Optically induced metal-to-dielectric transition in Epsilon-Near-Zero metamaterials
R. M. Kaipurath, M. Pietrzyk, L. Caspani +6
Epsilon-Near-Zero materials exhibit a transition in the real part of the dielectric permittivity from positive to negative value as a function of wavelength. Here we study metal-di…
Emergent geometries and nonlinear-wave dynamics in photon fluids
Francesco Marino, Calum Maitland, David Vocke +2
Nonlinear waves in defocusing media are investigated in the framework of the hydrodynamic description of light as a photon fluid. The observations are interpreted in terms of an em…
Phase-Insensitive Scattering of Terahertz Radiation
M. Petev, N. Westerberg, E. Rubino +6
The nonlinear interaction between Near-Infrared (NIR) and Terahertz pulses is principally investigated as a means for the detection of radiation in the hardly accessible THz spectr…
Experimental quantum cosmology in time-dependent optical media
N. Westerberg, S. Cacciatori, F. Belgiorno +2
It is possible to construct artificial spacetime geometries for light by using intense laser pulses that modify the spatiotemporal properties of an optical medium. Here we theoreti…
Blackbody emission from light interacting with an effective moving dispersive medium
M. Petev, N. Westerberg, D. Moss +5
Intense laser pulses excite a nonlinear polarisation response that may create an effective flowing medium and, under appropriate conditions, a blocking horizon for light. Here we a…
Soliton-induced relativistic-scattering and amplification
E. Rubino, A. Lotti, F. Belgiorno +4
Solitons are of fundamental importance in photonics due to applications in optical data transmission and also as a tool for investigating novel phenomena ranging from light generat…
Negative frequency resonant radiation
E. Rubino, J. McLenaghan, S. C. Kehr +7
Optical solitons or soliton-like states shed light to blue-shifted frequencies through a resonant emission process. We predict a mechanism by which a second propagating mode is gen…
Spacetime geometries and light trapping in travelling refractive index perturbations
F. Belgiorno, S. L. Cacciatori, V. Gorini +4
In the framework of transformation optics, we show that the propagation of a locally superluminal refractive index perturbation (RIP) in a Kerr medium can be described, in the eiko…
Dielectric black holes induced by a refractive index perturbation and the Hawking effect
F. Belgiorno, S. L. Cacciatori, G. Ortenzi +3
We consider a 4D model for photon production induced by a %superluminal refractive index perturbation in a dielectric medium. We show that, in this model, we can infer the presence…
Analogue Gravity and ultrashort laser pulse filamentation
D. Faccio, S. Cacciatori, V. Gorini +5
Ultrashort laser pulse filaments in dispersive nonlinear Kerr media induce a moving refractive index perturbation which modifies the space-time geometry as seen by co-propagating l…
