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…
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…
Co--propagating Bose--Einstein Condensates and electromagnetic radiation: Emission of mutually localized structures
Arkady Kim, Federica Cattani, Dan Anderson +1
Using a semi-classical model to describe the interaction between coherent electromagnetic radiation and a Bose-Einstein condensate in the limit of zero temperature, including the b…
Laser acceleration of ion bunches at the front surface of overdense plasmas
Andrea Macchi, Federica Cattani, Tatiana V. Liseykina +1
The acceleration of ions in the interaction of high intensity laser pulses with overdense plasmas is investigated with particle-in-cell simulations. For circular polarization of th…
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…
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…
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…
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…
Coupled-mode theory for Bose-Einstein condensates
Elena A. Ostrovskaya, Yuri S. Kivshar, Mietek Lisak +3
We apply the concepts of nonlinear guided-wave optics to a Bose-Einstein condensate (BEC) trapped in an external potential. As an example, we consider a parabolic double-well poten…
