“…It is used for the investigation of, e.g., supercontinuum [5], high harmonic [6], or terahertz generation [7], few-cycle pulse generation [8], or complex nonlinear dynamics as self-organization [9]. Analogies to other areas of physics as artificial event horizons [10] or the ubiquitous rogue wave formation [11][12][13] have been shown, providing a useful test for the investigation Hawking radiation [14] or the predictability of extreme events [15].…”

Regularizing Aperiodic Cycles of Resonant Radiation in Filament Light Bullets

We demonstrate an up to now unrecognized and very effective mechanism which prevents filament collapse and allows persistent self-guiding propagation retaining a large portion of the optical energy on axis over unexpected long distances. The key ingredient is the possibility of continuously leaking energy into the normal dispersion regime via the emission of resonant radiation. The frequency of the radiation is determined by the dispersion dynamically modified by photogenerated plasma, thus allowing us to excite new frequencies in spectral ranges which are otherwise difficult to access.

We studied the process of decoherence induced by the presence of an environment in acoustic black holes, using the open quantum system approach, thus extending previous work. We focused on the ion trap model but the formalism is general to any experimental implementation. We computed the decoherence time for that setup. We found that a quantum to classical transition occurs during the measurement and we proposed improved parameters to avoid such a feature. We provide analytic estimations for both zero and finite temperature. We also studied the entanglement between the Hawking-pair phonons for an acoustic black hole while in contact with a reservoir, through the quantum correlations, showing that they remain strongly correlated for small enough times and temperatures. We used the stochastic formalism and the method of characteristic to solve the field wave equation.

“…In 2008, Philbin et al [13] demonstrated the feasibility of creating artificial event horizons with a moving refractive-index front (RIF) in dispersive optical media. They estimated a temperature of 1000 K and ushered in the field of optical analogs [14][15][16][17]. The idea behind optical event horizons is to create a change in the refractive index, i.e., the speed of light, with light itself.…”

Quantum vacuum emission from a refractive-index front

A moving boundary separating two otherwise homogeneous regions of a dielectric is known to emit radiation from the quantum vacuum. An analytical framework based on the Hopfield model, describing a moving refractiveindex step in 1 + 1 dimensions for realistic dispersive media has been developed by S. Finazzi and I. Carusotto [Phys. Rev. A 87, 023803 (2013)]. We expand the use of this model to calculate explicitly spectra of all modes of positive and negative norms. Furthermore, for lower step heights we obtain a unique set of mode configurations encompassing black-hole and white-hole setups. This leads to a realistic emission spectrum featuring black-hole and white-hole emission for different frequencies. We also present spectra as measured in the laboratory frame that include all modes, in particular a dominant negative-norm mode, which is the partner mode in any Hawking-type emission. We find that the emission spectrum is highly structured into intervals of emission with black-hole, white-hole, and no horizons. Finally, we estimate the number of photons emitted as a function of the step height and find a power law of 2.5 for low step heights.
