[HTML][HTML] Dynamics of Bose–Einstein condensate in driven tilted optical lattices
AX Zhang, LX Cai, ZF Yu, NN Chang, SQ He, JK Xue - Physics Letters A, 2019 - Elsevier
We study the dynamics of Bose–Einstein condensate in one-dimensional driven tilted
periodic optical lattices by using variational approximation and numerical simulation. Rich
phenomena are revealed, including diffusion, self-trapping, breather and soliton, which
strongly depend on the atomic interaction, the amplitude of the modulation, the constant
force and the phase difference between the Bloch oscillations and the drive. The critical
conditions for the dynamical transition from diffusion to self-trapping and for the formation of …
