Dynamical transition in a nonlinear two-level system driven by a special hyperbolic-secant external field
We propose an exact solution to a linear two-level system with the existence of a special hyperbolic secant external field and elucidate its...

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...

Deformation scheme of nonlinear Rosen–Zener tunneling for Bose–Einstein condensates in a triple-well potential
We investigate Rosen–Zener tunneling for Bose–Einstein condensates in a triple-well potential within the framework of mean-field treatment. Firstly,...
