Low-lying energy levels of a one-dimensional weakly interacting Bose gas under zero boundary conditions
MD Tomchenko - arXiv preprint arXiv:1710.00326, 2017 - arxiv.org
We diagonalize the second-quantized Hamiltonian of a one-dimensional Bose gas with a
nonpoint repulsive interatomic potential and zero boundary conditions. At weak coupling the …

Quantum dark solitons in the 1d bose gas: From single to double dark-solitons
We study quantum double dark-solitons, which give pairs of notches in the density profiles,
by constructing corresponding quantum states in the Lieb–Liniger model for the one …
