Multi-band structure of the quantum bound states for a generalized nonlinear Schrodinger model
B. Basu-Mallick, Tanaya Bhattacharyya, Diptiman Sen
By using the method of coordinate Bethe ansatz, we study N-body bound states of a generalized nonlinear Schrodinger model having two real coupling constants c and η. It is found th…

Bound and anti-bound soliton states for a quantum integrable derivative nonlinear Schrodinger model
B. Basu-Mallick, Tanaya Bhattacharyya, Diptiman Sen
We find that localized quantum N-body soliton states exist for a derivative nonlinear Schrodinger (DNLS) model within an extended range of coupling constant (ξ_q) given by 0 < | ξ_…
