Theory of superfluidity and drag force in the one-dimensional Bose gas
Lieb-Liniger model, Tonks-Girardeau gas, Luttinger liquid, drag force, superfluidity, dynamical structure factor
2011/9/29
The one-dimensional Bose gas is an unusual superfluid. In contrast to higher spatial dimensions, the existence of non-classical rotational inertia is not directly linked to the dissipationless motion ...
Long timescale dynamics of spin textures in a degenerate F=1 $^{87}$ Rb spinor Bose gas
Long timescale dynamics spin textures Rb spinor Bose gas

Abstract: We investigate the long-term dynamics of spin textures prepared by cooling unmagnetized spinor gases of F=1 $^{87}$Rb to quantum degeneracy, observing domain coarsening and a strong dependen...
Periodic spin textures in a degenerate F=1 $^{87}$Rb spinor Bose gas
Periodic spin textures degenerate F=1 $^{87}$Rb spinor Bose gas

We report on the spin textures produced by cooling unmagnetized $^{87}$Rb F=1 spinor gases into the regime of quantum degeneracy. At low temperatures, magnetized textures form that break translational...
