One parameter family of rationally extended isospectral potentials
Rajesh Kumar Yadav, Suman Banerjee, Nisha Kumari +2
We start from a given one dimensional rationally extended potential associated with exceptional orthogonal polynomials and using the idea of supersymmetry in quantum mechanic…
Rationally extended many-body truncated Calogero-Sutherland model
Rajesh Kumar Yadav, Avinash Khare, Nisha Kumari +1
We construct a rational extension of the truncated Calogero-Sutherland model by Pittman et al. The exact solution of this rationally extended model is obtained analytically and it…
Role of conditional shape invariance symmetry property to obtain eigen-spectrum of the generalized polynomial potential with a Coulomb term
Sudesna Bera, Rajesh Kumar Yadav, Barnali Chakrabarti +1
A method based on supersymmteric (SUSY) quantum mechanics has been developed by exploiting conditional Shape invariance property for obtaining exact ground state solution of genera…
PT phase transition in higher-dimensional quantum systems
Bhabani Prasad Mandal, Brijesh Kumar Mourya, Rajesh Kumar Yadav
We consider a 2d anisotropic SHO with {\bf ixy} interaction and a 3d SHO in an imaginary magnetic field with . interaction to study the phase transition analy…
