Quantum liquidlike states of matter have been realized in an ongoing series of experiments
with ultracold Bose gases. Using a combination of analytical and numerical methods we …

Close to the demixing transition, the degree of freedom associated with relative density
fluctuations of a two-component Bose-Einstein condensate is described by a nondissipative …

We investigate a Bose-Bose mixture across the miscible-immiscible phase transition
governed by quantum fluctuations in one dimension. We find the recently predicted so …

We characterize the soliton solutions and their interactions for a system of coupled evolution
equations of nonlinear Schrödinger (NLS) type that models the dynamics in one …

We outline a program to classify domain walls (DWs) and vector solitons in the 1D two-
component coupled nonlinear Schrödinger (CNLS) equation without restricting the signs or …

Quantum liquid-like states of matter have been realized in an ongoing series of experiments
with ultracold Bose gases. By means of analytical and theoretical methods we identify the …

We systematically construct a series of vector solitary waves in harmonically trapped one-
dimensional three-, four-, and five-component Bose-Einstein condensates. These stationary …

We investigate the dynamics of beating solitons in a two-component Bose–Einstein
condensate with tunable Rabi coupling strength. Our results demonstrate that the balance …

We theoretically study the resonant phenomenon in a spin-1 Bose-Einstein condensate
periodically driven by a quadratic Zeeman coupling. This phenomenon is closely related to …

We develop an analytical description of static ferrodark solitons, the Z 2 topological defects
in the magnetic order, in the easy-plane phase of ferromagnetic spin-1 Bose-Einstein …
