Quantum dark solitons in the 1D Bose gas: From single to double dark-solitons

Kayo Kinjo, Eriko Kaminishi, Takashi Mori +3

We study quantum double dark-solitons by constructing corresponding quantum states in the Lieb-Liniger model for the one-dimensional Bose gas. Here we expect that the Gross-Pitaevs…
