Abstract: We consider matter-wave bright solitons in helicoidal spin-orbit coupled Bose–Einstein condensates in optical lattices with a view to study Josephson-type oscillation and self-trapping of population imbalance between two pseudo-spin states. For fixed values of nonlinear… read more here.

DOI: 10.1103/physreva.104.033325
Abstract: The paper studies the modulational instability (MI), both theoretically and numerically, of the helicoidal spin-orbit coupled Bose-Bose mixture. An expression of the MI growth rate is found through the linear stability analysis of continuous wave,… read more here.

DOI: 10.1103/physreve.109.064219
Abstract: We investigate the existence and stability of higher-order bright solitons, stripe solitons, and bright-dark solitons in a Bose-Einstein condensate with helicoidal spin-orbit coupling under a Zeeman lattice using numerical methods. The higher-order bright solitons that… read more here.
