Semiclassical dynamics of a dark soliton in a one-dimensional bosonic superfluid in an optical lattice
We study quantum dynamics of a dark soliton in a one-dimensional Bose gas in an optical lattice within the truncated Wigner approximation. Previous work has revealed that in the absence of quantum fluctuations, dynamical stability of the dark soliton significantly depends on whether its phase kink i...
