Dynamical suppression of tunneling and spin switching of a spin-orbit-coupled atom in a double-well trap

Publikováno v: Physical Review A. 97

We predict wide-band suppression of tunneling of spin-orbit-coupled atoms (or noninteracting Bose-Einstein condensate) in a double-well potential with periodically varying depths of the potential wells. The suppression of tunneling is possible for a

We show that media with inhomogeneous defocusing cubic nonlinearity growing toward the periphery can support a variety of stable vortex clusters nested in a common localized envelope. Nonrotating symmetric clusters are built of an even number of vort

Localized waves supported by the rotating waveguide array

Autor: Xiao Zhang, Yaroslav V. Kartashov, Fangwei Ye, Xianfeng Chen, Victor A. Vysloukh

We show that truncated rotating square waveguide arrays support new types of localized modes that exist even in the linear case, in complete contrast to localized excitations in nonrotating arrays requiring nonlinearity for their existence and formin

Publikováno v: Quantum Electronics. 34:457-460

A new class of stationary periodic solutions of the nonlinear wave Schrodinger equation is studied taking the third-order group-velocity dispersion into account and their main properties and regions of existence are analysed. It is shown that a perio
