Singularity of Berry Connections Inhibits the Accuracy of Adiabatic Approximation
Jie Liu, Li-Bin Fu
Adiabatic approximation for quantum evolution is investigated quantitatively with addressing its dependence on the Berry connections. We find that, in the adiabatic limit, the adia…
Irregular Spin Tunnelling for Spin-1 Bose-Einstein Condensates in a Sweeping Magnetic Field
Guan-Fang Wang, Li-Bin Fu, Jie Liu
We investigate the spin tunnelling of spin-1 Bose-Einstein condensates in a linearly sweeping magnetic field with a mean-field treatment. We focus on the two typical alkali Bose at…
Quantum Entanglement Manifestation of Transition to Nonlinear Self-trapping for Bose-Einstein Condensates in a Symmetric Double-Well

In present paper we develop an analytic theory for the harmonic generation of symmetric diatomic molecular ions beyond two-level model, emphasizing the influence of charge-resonanc…
Evolution of SU(4) Transport Regimes in Carbon Nanotube Quantum Dots
A. Makarovski, J. Liu, G. Finkelstein
We study the evolution of conductance regimes in carbon nanotubes with doubly degenerate orbitals (``shells'') by controlling the contact transparency within the same sample. For s…
Landau-Zener Tunnelling in a Nonlinear Three-level System
Guan-Fang Wang, Di-Fa Ye, Li-Bin Fu +2
We present a comprehensive analysis of the Landau-Zener tunnelling of a nonlinear three-level system in a linearly sweeping external field. We find the presence of nonzero tunnelli…
Collective excitations of a Bose-Einstein condensate in an anharmonic trap
Guan-Qiang Li, Li-Bin Fu, Ju-Kui Xue +2
We investigate the collective excitations of a one-dimensional Bose-Einstein condensate (BEC) with repulsive interaction between atoms in a quadratic plus quartic trap. By using th…

We investigate the quantum dynamics of a periodically kicked Bose-Einstein Condensate confined in a one dimensional (1D) Box both numerically and theoretically, emphasizing on the…
Self-trapping of Bose-Einstein condensates in optical lattices
Bingbing Wang, Panming Fu, Jie Liu +1
The self-trapping phenomenon of Bose-Einstein condensates (BECs) in optical lattices is studied extensively by numerically solving the Gross-Pitaevskii equation. Our numerical resu…
