Localization of ultracold atoms in incommensurate spin-orbit-coupling and Zeeman lattices
Dmitry A. Zezyulin, Vladimir V. Konotop
We consider a particle governed by a one-dimensional Hamiltonian in which artificial periodic spin-orbit coupling and Zeeman lattice have incommensurate periods. Using best rationa…
Stable two-dimensional soliton complexes in Bose-Einstein condensates with helicoidal spin-orbit coupling
Ya. V. Kartashov, E. Ya. Sherman, B. A. Malomed +1
We show that attractive two-dimensional spinor Bose-Einstein condensates with helicoidal spatially periodic spin-orbit coupling (SOC) support a rich variety of stable fundamental s…
Coherent perfect absorption of nonlinear matter waves
Andreas Müllers, Bodhaditya Santra, Christian Baals +6
Coherent perfect absorption is the complete extinction of incoming radiation by a complex potential in a physical system supporting wave propagation. The concept was proven for lin…
Spin-orbit coupled soliton in a random potential
Sh. Mardonov, V. V. Konotop, B. A. Malomed +2
We investigate theoretically the dynamics of a spin-orbit coupled soliton formed by a self- interacting Bose-Einstein condensate immersed in a random potential, in the presence of…
Observation and uses of position-space Bloch oscillations in an ultracold gas
Zachary A. Geiger, Kurt M. Fujiwara, Kevin Singh +8
We report the direct observation and characterization of position-space Bloch oscillations using an ultracold gas in a tilted optical lattice. While Bloch oscillations in momentum…
Stationary through-flows in a Bose-Einstein condensate with a PT-symmetric impurity
Dmitry A. Zezyulin, I. V. Barashenkov, Vladimir V. Konotop
Superfluid currents in the boson condensate with a source and sink of particles are modelled by the PT-symmetric Gross-Pitaevskii equation with a complex potential. We demonstrate…
Gap solitons in the spin-orbit coupled Bose-Einstein condensates
Yaroslav V. Kartashov, Vladimir V. Konotop, Fatkhulla Kh. Abdullaev
We report a diversity of stable gap solitons in a spin-orbit coupled Bose-Einstein condensate subject to a spatially periodic Zeeman field. It is shown that the solitons, can be cl…
Nonlinear modes in binary bosonic condensates with the pseudo-spin-orbital coupling
D. A. Zezyulin, R. Driben, V. V. Konotop +1
We consider a binary Bose-Einstein condensate (BEC) with nonlinear repulsive interactions and linear spin-orbit (SO) and Zeeman-splitting couplings. In the presence of the trapping…
Superfluidity of Bose-Einstein condensates in toroidal traps with nonlinear lattices
A. V. Yulin, Yu. V. Bludov, V. V. Konotop +2
Superfluid properties of Bose-Einstein condensates (BEC) in toroidal quasi-one-dimensional traps are investigated in the presence of periodic scattering length modulations along th…
Nonlinear localized modes in dipolar Bose-Einstein condensates in optical lattices
S. Rojas-Rojas, R. A. Vicencio, M. I. Molina +1
The modulational instability and discrete matter wave solitons in dipolar BEC, loaded into a deep optical lattice, are investigated analytically and numerically. The process of mod…
Control of the Bose-Einstein condensate by dissipation. Nonlinear Zeno effect
V. S. Shchesnovich, V. V. Konotop
We show that controlled dissipation can be used as a tool for exploring fundamental phenomena and managing mesoscopic systems of cold atoms and Bose-Einstein condensates. Even the…
