Point Process Models of 1/f Noise and Internet Traffic
V. Gontis, B. Kaulakys, J. Ruseckas
We present a simple model reproducing the long-range autocorrelations and the power spectrum of the web traffic. The model assumes the traffic as Poisson flow of files with size di…
Non-Abelian gauge potentials for ultra-cold atoms with degenerate dark states
J. Ruseckas, G. Juzeliunas, P. Oehberg +1
We show that the adiabatic motion of ultra-cold, multi-level atoms in spatially varying laser fields can give rise to effective non-Abelian gauge fields if degenerate adiabatic eig…
Effective magnetic fields in degenerate atomic gases induced by light beams with orbital angular momenta
G. Juzeliunas, P. Ohberg, J. Ruseckas +1
We investigate the influence of two resonant laser beams on the mechanical properties of degenerate atomic gases. The control and probe beams of light are considered to have Orbita…
Space-time nonlinear compression and three-dimensional complex trapping in normal dispersion
G. Valiulis, J. Kilius, O. Jedrkiewicz +6
In positive phase-mismatched SHG and normal dispersion, a gaussian spatio-temporal pulse transforms spontaneously into a X-pulse, underlies spatio-temporal compression and eventual…
