Construction and exact solution of a nonlinear quantum field model in quasi-higher dimension
Anjan Kundu
Nonperturbative exact solutions are allowed for quantum integrable models in one space-dimension. Going beyond this class we propose an alternative Lax matrix approach, exploiting…
Quantum and classical integrable sine-Gordon model with defect
Ismagil Habibullin, Anjan Kundu
Defects which are predominant in a realistic model, usually spoil its integrability or solvability. We on the other hand show the exact integrability of a known sine-Gordon field m…
Shape changing and accelerating solitons in integrable variable mass sine-Gordon model
Anjan Kundu
Sine-Gordon model with variable mass (VMSG) appears in many physical systems, ranging from the current through nonuniform Josephson junction to DNA-promoter dynamics. Such models a…
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…
Unifying Approaches in Integrable Systems: Quantum and Statistical, Ultralocal and Nonultralocal
Anjan Kundu
The aim of this review is to present the list of by now a significant collection of quantum integrable models, ultralocal as well as nonultralocal, in a systematic way stressing on…
Ultralocal solutions for quantum integrable nonultralocal models
Anjan Kundu
A challenge in the theory of integrable systems is to show for every nonultralocal quantum integrable model, a possible connection to an ultralocal model. Some of such gauge connec…
