Devil's staircases without particle-hole symmetry
Zhihao Lan, Igor Lesanovsky, Weibin Li
We present and analyze spin models with long-range interactions whose ground state features a so-called devil's staircase and where plateaus of the staircase are accessed by varyin…
Directly determining the relative phase of two coherent solitary waves in attractive Bose-Einstein condensates
Weibin Li
We study the dynamic structure factor of two coherent bright solitary waves in attractive Bose- Einstein condensates confined in a harmonic trap. We demonstrate that the wave funct…
Quantum reflection: The invisible quantum barrier
J. X. de Carvalho, M. S. Hussein, Weibin Li
We construct the invisible quantum barrier which represents the phenomenon of quantum reflection using the available data. We use the Abel equation to invert the data. The resultin…
A vortex dipole in a trapped two-dimensional Bose-Einstein condensate
Weibin Li, Masudul Haque, Stavros Komineas
We study the conservative dynamics and stationary configurations of a vortex-antivortex pair in a harmonically trapped two-dimensional Bose-Einstein condensate. We establish the co…
Correlation and entanglement of two-component Bose-Einstein condensates in a double well
Weibin Li, Wenxing Yang, Xiaotao Xie +2
We consider a novel system of two-component atomic Bose-Einstein condensate in a double-well potential. Based on the well-known two-mode approximation, we demonstrate that there ar…
Many-body dynamics of a Bose system with attractive interactions on a ring
Weibin Li, Xiaotao Xie, Zhiming Zhan +1
We investigate the many-body dynamics of an effectively attractive one-dimensional Bose system confined in a toroidal trap. The mean-field theory predicts that a bright-soliton sta…
