Abstract: Abstract Using an operator approach based on a commutator scheme that has been previously applied to Richardson’s reduced BCS model and the inhomogeneous Dicke model, we obtain general exact solvability requirements for an anisotropic central… read more here.

DOI: 10.1016/j.physa.2020.124406
Abstract: Building on our earlier work \unscite{Sa-Za}, we introduce and study generalized XX0 models. We explicitly construct a long-range interacting spin chain, referred to as the Selberg model, and study the correlation functions of the Selberg… read more here.

DOI: 10.1142/s0217732318501870
Abstract: This work aims at introducing two new solvable 1D and 3D confined potentials and present their solutions using the Tridiagonal Representation Approach (TRA). The wave function is written as a series in terms of square… read more here.
