G. E. Gurgenishvili, G. A. Kharadze, L. A. Chobanian


Abstract: The one-dimensional system consisting of $N-1$ identical particles (bosons) and one “impurity” particle is considered. The equation for wave numbers $\{k\}$ defining the energy of the system is obtained. The limiting case of infinitely strong repulsion between Bose-particles is investigated.
