Нижні енергетичні рівні одновимірного слабко взаємодіючого бозе-газу з нульовими межовими умовами
We diagonalize the second-quantized Hamiltonian of a one-dimensional Bose gas with a non-point repulsive interatomic potential and zero boundary conditions. At a weak coupling, the solutions for the ground-state energy E0 and the dispersion law E(k) coincide with the Bogoliubov solutions for a perio...
