Among this,we show that transverse Bloch waves excited in arrays of one-dimensional coupled condensates cancarry tunneling superflows whose dynamical stability depends on the quasimomentum. Across thestacks with periodic boundary conditions, forming closed ring-shaped systems, such Bloch states yieldtransverse Josephson vortices with a generic non-integer circulation in units ofh/m. Additionally, thesuperpositions of degenerate linear Bloch waves can suppress the supercurrents and give rise tofamilies of nonlinear standing-wave states with strong(transverse)spatial localization. Stable states ofthis type can also be found infinite size systems.17 p.application/pdfeng(c) IOP Publishing Ltd and Deutsche Physikalische Gesellschaft, 2019Condensació de Bose-EinsteinOnes no linealsEfecte túnelBose-Einstein condensationNonlinear wavesTunneling (Physics)info:eu-repo/semantics/article6897862019-04-23info:eu-repo/semantics/openAccess
