Quantized transport of solitons in Bose-Einstein condensates driven by spin-orbit coupling
Yaroslav V. Kartashov, Vladimir V. Konotop, Dmitry A. Zezyulin
We demonstrate that linear and nonlinear Thouless pumping can be realized in two-component elongated Bose-Einstein condensates using helicoidal spin-orbit coupling that slides with…
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…
Quasi-one-dimensional harmonically trapped quantum droplets
Dmitry A. Zezyulin
We theoretically consider effectively one-dimensional quantum droplets in a symmetric Bose-Bose mixture confined in a parabolic trap. We systematically investigate ground and excit…
Bose-Einstein condensates in quasi-periodic lattices: bosonic Josephson junction, self-trapping, and multi-mode dynamics
Henrique C. Prates, Dmitry A. Zezyulin, Vladimir V. Konotop
Bose-Einstein condensates loaded in one-dimensional bichromatic optical lattices with constituent sublattices having incommensurate periods is considered. Using the rational approx…
