Non-equilibrium Green's function formalism and the problem of bound states
Abhishek Dhar, Diptiman Sen
The non-equilibrium Green's function formalism for infinitely extended reservoirs coupled to a finite system can be derived by solving the equations of motion for a tight-binding H…

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…
