Computer model validation with functional output
M. J. Bayarri, J. O. Berger, J. Cafeo +7
A key question in evaluation of computer models is Does the computer model adequately represent reality? A six-step process for computer model validation is set out in Bayarri et a…
Field patterns in periodically modulated optical parametric amplifiers and oscillators
V. A. Brazhnyi, V. V. Konotop, S. Coulibaly +1
Spatially localized and periodic field patterns in periodically modulated optical parametric amplifiers and oscillators are studied. In the degenerate case (equal signal and idler…
Laser tweezers for atomic solitons
Alicia V. Carpentier, Juan Belmonte-Beitia, Humberto Michinel +1
We describe a controllable and precise laser tweezers for Bose-Einstein condensates of ultracold atomic gases. In our configuration, a laser beam is used to locally modify the sign…
Filamentation instability in a quantum plasma
A. Bret
The growth rate of the filamentation instability triggered when a diluted cold electron beam passes through a cold plasma is evaluated using the quantum hydrodynamic equations. Com…
Delocalizing transition in one-dimensional condensates in optical lattices due to inhomogeneous interactions
Yu. V. Bludov, V. A. Brazhnyi, V. V. Konotop
It is shown that inhomogeneous nonlinear interactions in a Bose-Einstein condensate loaded in an optical lattice can result in delocalizing transition in one dimension, what sharpl…
Acceleration and localization of matter in a ring trap
Yu. V. Bludov, V. V. Konotop
A toroidal trap combined with external time-dependent electric field can be used for implementing different dynamical regimes of matter waves. In particular, we show that dynamical…
