Bound and scattering states of extended Calogero model with an additional PT invariant interaction
B. Basu-Mallick, Tanaya Bhattacharyya, Anjan Kundu +1
Here we discuss two many-particle quantum systems, which are obtained by adding some nonhermitian but PT (i.e. combined parity and time reversal) invariant interaction to the Calog…
Exact solvability and quantum integrability of a derivative nonlinear Schrodinger model
B. Basu-Mallick, Tanaya Bhattacharyya
By using a variant of quantum inverse scattering method (QISM) which is directly applicable to field theoretical systems, we derive all possible commutation relations among the ope…
Novel multi-band quantum soliton states for a derivative nonlinear Schrodinger model
B. Basu-Mallick, Tanaya Bhattacharyya, Diptiman Sen
We show that localized N-body soliton states exist for a quantum integrable derivative nonlinear Schrodinger model for several non-overlapping ranges (called bands) of the coupling…
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_…
Near-Horizon States of Black Holes and Calogero Models
B Basu-Mallick, Pijush K. Ghosh, Kumar S. Gupta
We find self-adjoint extensions of the rational Calogero model in presence of the harmonic interaction. The corresponding eigenfunctions may describe the near-horizon quantum state…
Jost solutions and quantum conserved quantities of an integrable derivative nonlinear Schrodinger model
B. Basu-Mallick, Tanaya Bhattacharyya
We study differential and integral relations for the quantum Jost solutions associated with an integrable derivative nonlinear Schrodinger (DNLS) model. By using commutation relati…
