Nonlinear wave dynamics in photonic time crystals
Fabio Biancalana
Maxwell's wave equation in the presence of a cubic nonlinearity and a periodically time-varying refractive index (a photonic time crystal) is reduced, for spatially monochromatic w…
Real-time identification of the onset of financial rogue waves
Rosie Hayward, Orla Lennon, Fabio Biancalana
Extreme events in financial systems, often captured by indicators such as volatility, remain difficult to identify close to their onset. Volatility shares many statistical properti…
Reduction of nonlinear field theory equations to envelope models: towards a universal understanding of analogues of relativistic systems
Charles W. Robson, Fabio Biancalana
We investigate a novel mapping between solutions to several members of the Klein-Gordon family of equations and solutions to equations describing their reductions via the slowly va…
Generation of Half-Integer Harmonics and Efficient THz-to-Visible Frequency Conversion in Strained Graphene
Marco Ornigotti, Luca Ornigotti, Fabio Biancalana
We study the generation of harmonics from graphene under the influence of an artificial magnetic field, generated via bending of a graphene flake. We show how the Landau level stru…
Convergence of Combinatorial Gravity
Christy Kelly, Carlo Trugenberger, Fabio Biancalana
We present a new regularisation of Euclidean Einstein gravity in terms of (sequences of) graphs. In particular, we define a discrete Einstein-Hilbert action that converges to its m…
Ultra-broadband supercontinuum generation in gas-filled photonic-crystal fibers: The epsilon-near-zero regime
Mohammed F. Saleh, Fabio Biancalana
In this Letter, we show theoretically that the nonlinear photoionisation process of a noble gas inside a hollow-core photonic crystal fibre can be exploited in obtaining broadband…
