Comment on "Hawking radiation from ultrashort laser pulse filaments".
In a recent paper [1] Belgiorno et al claimed to have observed the analog of the Hawking effect created by light pulses in silica glass because of the detection of radiation in a frequency range in which what they called " phase horizons " existed. Unfortunately, while the observations are very interesting, the cause of the radiation is not understood, and we feel it is not justified to call th...
متن کاملHawking radiation from ultrashort laser pulse filaments.
Event horizons of astrophysical black holes and gravitational analogues have been predicted to excite the quantum vacuum and give rise to the emission of quanta, known as Hawking radiation. We experimentally create such a gravitational analogue using ultrashort laser pulse filaments and our measurements demonstrate a spontaneous emission of photons that confirms theoretical predictions.
متن کاملComment on " Vanishing Hawking Radiation from a Uniformly
We argue that the analysis of transients, of decoherence effects, or of any breaking of the exact boost invariance of the Ernst metric shows that uniformly accelerated black holes do emit an energy flux given by the Doppler-shifted Hawking radiation, in perfect agreement to what happens for accelerated particles.
متن کاملElectron in the Ultrashort Laser Pulse
After the clasical approach to acceleration of a charged particle by δ-form impulsive force, we consider the corresponding quantum theory based on the Volkov solution of the Dirac equation. We determine the modified Compton formula for frequency of photons generated by the scattering of the δ-form laser pulse on the electron in a rest.
متن کاملUltrashort Laser Pulse Propagation in Water
The major objectives of this proposal are twofold. The first objective is to perform both an experimental and theoretical study of the factors affecting the propagation distance behavior of ultrashort (femtosecond) laser pulses in water. This study will be conducted in the so-called linear regime which involves laser intensities that are below the threshold where nonlinear effects set in. A fun...
