Determination of the carrier envelope phase for short, circularly polarized laser pulses
Alexander I. Titov, Burkhard Kampfer, Atsushi Hosaka +2
We analyze the impact of the carrier envelope phase on the differential cross sections of the Breit-Wheeler and the generalized Compton scattering in the interaction of a charged e…
The Pegg-Barnett phase operator and the discrete Fourier transform
A. Perez-Leija, L. A. Andrade-Morales, F. Soto-Eguibar +2
In quantum mechanics the position and momentum operators are related to each other via the Fourier transform. In the same way, here we show that the so-called Pegg-Barnett phase op…
Avalanche effect and gain saturation in high harmonic generation
Carles Serrat, David Roca, Josep M. Budesca +7
Optical amplifiers in all ranges of the electromagnetic spectrum exhibit two essential characteristics: i) the input signal during the propagation in the medium is multiplied by th…
The spectacular evolution of Supernova 1996al over 15 years: a low energy explosion of a stripped massive star in a highly structured environment
Stefano Benetti, Nikolai N. Chugai, Victor P. Utrobin +9
Spectrophotometry of SN 1996al carried out throughout 15 years is presented. The early photometry suggests that SN 1996al is a Linear type-II supernova, with an absolute peak of Mv…
Direct measurement of second-order coupling in a waveguide lattice
Robert Keil, Benedikt Pressl, René Heilmann +3
We measure the next-nearest-neighbour coupling in an array of coupled optical waveguides directly via an integrated eigenmode interferometer. In contrast to light propagation exper…
On the effect of time-dependent inhomogeneous magnetic fields in electron-positron pair production
Christian Kohlfürst, Reinhard Alkofer
Electron-positron pair production in space- and time-dependent electromagnetic fields is investigated. Especially, the influence of a time-dependent, inhomogeneous magnetic field o…
