Supercurrent stability in a quasi-one-dimensional weakly interacting Bose gas
Supercurrent stability in a quasi-one-dimensional weakly interacting Bose gas
We discuss the possibility of observing superfluid phenomena in a quasi-one-dimensional weakly interacting Bose gas at finite temperature. The weakness of interaction in combination with generic properties of one-dimensional liquids can result in a situation where the relaxation time of the supercurrent flow is much longer than the system lifetime, …
