Two-surface wave decay: improved analytical theory and effects on electron acceleration
A. Macchi, M. Battaglini, F. Cattani +1
Two-surface wave decay (TSWD), i.e. the parametric excitation of electron surface waves, was recently proposed as an absorption mechanism in the interaction of ultrashort, intense…
Measuring and engineering entropy and spin squeezing in weakly linked Bose-Einstein condensates
F. Cattani, C. Gross, M. K. Oberthaler +1
We propose a method to infer the single-particle entropy of bosonic atoms in an optical lattice and to study the local evolution of entropy, spin squeezing, and entropic inequaliti…
A new regime of anomalous penetration of relativistically strong laser radiation into an overdense plasma
A. Kim, F. Cattani, D. Anderson +1
It is shown that penetration of relativistically intense laser light into an overdense plasma, accessible by self-induced transparency, occurs over a finite length only. The penetr…
Fermat's principle and variational analysis of an optical model for light propagation exhibiting a critical radius
M. Marklund, D. Anderson, F. Cattani +2
Fermat's principle and variational analysis is used to analyze the trajectories of light propagating in a radially inhomogeneous medium with a singularity in the center. It is foun…
Multi-filament structures in relativistic self-focusing
F. Cattani, A. Kim, D. Anderson +1
A simple model is derived to prove the multi-filament structure of relativistic self-focusing with ultra-intense lasers. Exact analytical solutions describing the transverse struct…
Multi--hump soliton--like structures in interactions of lasers and Bose--Einstein condensates
F. Cattani, A. Kim, T. Hansson +2
An investigation is made of multi-hump and periodic solutions of the semi-classical coupled equations describing laser radiation copropagating with a Bose-Einstein condensate. Solu…
Electromagnetic energy penetration in the self-induced transparency regime of relativistic laser-plasma interactions
M. Tushentsov, F. Cattani, A. Kim +2
Two scenarios for the penetration of relativistically intense laser radiation into an overdense plasma, accessible by self-induced transparency, are presented. For supercritical de…
