Formation of nonlinear modes in one-dimensional quasiperiodic lattices with a mobility edge
Dmitry A. Zezyulin, Georgy L. Alfimov
We investigate the formation of steady states in one-dimensional Bose-Einstein condensates of repulsively interacting ultracold atoms loaded into a quasiperiodic potential created…
Double-flattop quantum droplets in low-dimensional Bose-Bose mixtures
Yaroslav V. Kartashov, Dmitry A. Zezyulin
We predict the existence of double-flattop quantum droplets in atomic Bose-Bose mixtures. Solutions of this type have two flattop regions of nearly uniform atomic density correspon…
Multipole quantum droplets in quasi-one-dimensional asymmetric mixtures
Yaroslav V. Kartashov, Dmitry A. Zezyulin
We study quantum droplets emerging in a quasi-one-dimensional asymmetric mixture of two atomic species with different intra-component coupling constants. We find that such mixtures…
Enhanced mobility of quantum droplets in periodic lattices
Yaroslav V. Kartashov, Dmitry A. Zezyulin
We predict that one- and two-dimensional self-bound quantum droplets, forming in Bose-Einstein condensates in the presence of Lee-Huang-Yang (LHY) quantum corrections to the mean-f…
Stability restoration by asymmetric nonlinear states in non-Hermitian double-well potentials
Dmitry A. Zezyulin
We introduce a class of one-dimensional complex optical potentials that feature a nonlinearity-induced stability restoration, i.e., the existence of stable nonlinear modes propagat…
Multistable localized states in highly photonic polariton rings with a quasiperiodic modulation
Andrei V. Nikitin, Dmitry A. Zezyulin
We present a theoretical study of an exciton-polariton annular microcavity with an additional quasiperiodic structure along the ring which is implemented in the form of a bicosine…
