Ground State Properties of Cold Bosonic Atoms At Large Scattering Lengths
Jun Liang Song, Fei Zhou
In this letter, we study bosonic atoms at large scattering lengths using a variational method where the condensation amplitude is a variational parameter. We further examine moment…
Dynamical Creation of Fractionalized Vortices and Vortex Lattices
An-Chun Ji, W. M. Liu, Jun Liang Song +1
We investigate dynamic creation of fractionalized half-quantum vortices in Bose-Einstein condensates of sodium atoms. Our simulations show that both individual half-quantum vortice…
Tunable Quantum Fluctuation-Controlled Coherent Spin Dynamics
Jun Liang Song, Fei Zhou
Temporal evolution of a macroscopic condensate of ultra cold atoms is usually driven by mean field potentials, either due to scattering between atoms or due to coupling to external…
Quantum Entanglement in the S=1/2 Spin Ladder with Ring Exchange
Jun-Liang Song, Shi-Jian Gu, Hai-Qing Lin
In this paper we study the concurrence and the block-block entanglement in the spin ladder with four-spin ring exchange by the exact diagonalization method of finite cluste…
Local entanglement and quantum phase transition in 1D transverse field Ising model
Shi-Quan Su, Jun-Liang Song, Shi-Jian Gu
In this paper, we study the entanglement between two-neighboring sites and the rest of the system in a simple quantum phase transition of 1D transverse field Ising model. We find t…
