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…
Fluctuation-Driven Vortex Fractionalization in Topologically Ordered Superfluids of Cold Atoms
Jun Liang Song, Fei Zhou
We have studied spin structures of fluctuation-driven fractionalized vortices and topological spin order in 2D nematic superfluids of cold sodium atoms. Our Monte Carlo simulations…
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 fluctuation-induced uniaxial and biaxial spin nematics
Jun Liang Song, Gordon W. Semenoff, Fei Zhou
It is shown that zero point quantum fluctuations (ZPQFs) completely lift the accidental continuous degeneracy that is found in mean field analysis of quantum spin nematic phases of…
