    Adiabatic light propagation in nonlinear waveguide couplers with longitudinally varying detunings via resonance-locked inverse engineering

    We investigate the adiabatic evolution of light in nonlinear waveguide couplers via resonance-locked inverse engineering based on stimulated Raman adiabatic passage (STIRAP). The longitudinal varying detunings...

    Landau–Zener–Stückelberg–Majorana interference of a spin-orbit-coupled Bose–Einstein condensate

    The spin-orbit-coupled (SOC) ultracold atomic gases provide unique opportunities for exploring exotic quantum phases and introduce new capabilities into the quantum simulation. In this paper, we study the cohe...

    Interaction induced localization of a spin–orbit-coupled Bose-Einstein condensate in a double-well potential

    We investigate atomic interaction induced localization of a spin–orbit coupled Bose-Einstein condensate loaded in a double-well potential. We confirm the existence of the localization in the presence of the s...

    Demkov–Kunike transition dynamics in a nonlinear two-level system

    We investigate the Demkov–Kunike transition in a nonlinear two-level system. We find that nonlinearity can dramatically affect the transition dynamics. We show the asymmetry of transition probability in differ...

    Coherent control of spin-orbit-coupled atom in a double-well potential

    We study coherent control of a spin-orbit-coupled single atom in a double-well potential. The manipulation is achieved by applying an additional periodic driven magnetic field gradient to generate the spin-de...

    Coupled Korteweg de Vries solitary wave of superfluid Bose-Fermi mixture

    In this paper, the solitary waves in superfluid Bose-Fermi mixture are investigated under the limited case of a BEC regime, a BCS regime and unitarity. By using the transverse perturbation method, a coupled Ko...

    Self-trap** and its periodic modulation of superfluid Fermi gases in one-dimensional accelerating optical lattice from BEC to unitarity regime

    We study the tunneling dynamics of superfluid Fermi gases in an optical lattice from BEC to unitarity regime. Four different cases are found, namely Josephson oscillations (JO), oscillating-phase-type self-tra...
