Josephson Oscillation and Nonlinear Self-Trapping in Quasi-one-dimensional Quantum Liquid
The study investigates Josephson oscillation and nonlinear self-trapping in quasi-one-dimensional quantum liquids using a two-mode method to account for mean-field, beyond mean-field, and three-body interactions. The research shows that the Josephson frequency is non-monotonic with particle number in one dimension and asymmetry affects the interaction competition effects.
