Dynamical control of particle jets from a driven condensate in a one-dimensional lattice with double-well potential
Z. Li, L. Q. Lai
We investigate the nonlinear dynamics of a Bose-Einstein condensate trapped in a double-well potential of a one-dimensional lattice, where the interatomic interactions are periodic…

Generally covariant geometric momentum and geometric potential for a Dirac fermion on a two-dimensional hypersurface
Z. Li, L. Q. Lai
Geometric momentum is the appropriate momentum for a particle constrained to move on a curved surface, which depends on the extrinsic curvature and leads to observable effects, and…
