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…
Instability and particle current control of a parametrically driven Bose-Einstein condensate in a ring-shaped lattice
L. Q. Lai
We investigate the dynamics of a Bose-Einstein condensate in a one-dimensional ring-shaped lattice with the Peierls phase and site-dependent modulations, where the condensate is co…
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…
Interference-induced suppression of particle emission from a Bose-Einstein condensate in lattice with time-periodic modulations
L. Q. Lai, Z. Li
Emission of matter-wave jets from a parametrically driven condensate has attracted significant experimental and theoretical attention due to the appealing visual effects and potent…
Intermittent emission of particles from a Bose-Einstein condensate in a one-dimensional lattice
L. Q. Lai, Z. Li, Q. H. Liu +1
We investigate particle emission from a Bose-Einstein condensate with periodically modulated interactions in a one-dimensional lattice. Within perturbative analysis, which leads to…
Resonant enhancement of particle emission from a parametrically driven condensate in a one-dimensional lattice
L. Q. Lai, Y. B. Yu, Erich J. Mueller
Motivated by recent experiments, we investigate particle emission from a Bose-Einstein condensate in a one-dimensional lattice, where the interaction strength is periodically modul…
Emission of particles from a parametrically driven condensate in a one-dimensional lattice
L. Q. Lai, Y. B. Yu, Erich J. Mueller
Motivated by recent experiments, we calculate particle emission from a Bose-Einstein condensate trapped in a single deep well of a one-dimensional lattice when the interaction stre…
The curvature-induced gauge potential and the geometric momentum for a particle on a hypersphere
Z. Li, L. Q. Lai, Y. Zhong +1
A particle that is constrained to freely move on a hyperspherical surface in an dimensional flat space experiences a curvature-induced gauge potential, who…
Charge nonconservation of molecular devices in the presence of a nonlocal potential
L. Q. Lai, J. Chen, Q. H. Liu +1
In the presence of a nonlocal potential in molecular device systems, generally the charge conservation cannot be satisfied, and in literatures the modifications of the conventional…
