Journal ArticleDOI
Supersymmetry in Quantum Mechanics
A. Lahiri,P. K. Roy,Bijan Bagchi +2 more
TL;DR: In this paper, a pedagogical review on supersymmetry in quantum mechanis is presented which provides a comprehensive coverage of the subject and the key ingredients on the quantization of the systems with anticommuting variables are discussed.
Journal ArticleDOI
Supersymmetry in atomic physics and the radial problem
TL;DR: In this paper, a correct procedure for constructing supersymmetry in 3D is presented and the degeneracies are found between states of the same l but different n and Z and the previous results on the Coulomb and the three-dimensional isotropic oscillator problems are reestablished.
Journal ArticleDOI
Supersymmetry and the three-dimensional isotropic oscillator problem
A. Lahiri,P. K. Roy,Bijan Bagchi +2 more
TL;DR: By transforming the radial equation of the isotropic oscillator to the Coulomb form, this paper showed that the energy degeneracy of the three-dimensional oscillator may be understood on account of supersymmetry.
Journal ArticleDOI
Conservation laws, Korteweg-de Vries and sine-Gordon systems, and the role of supersymmetry.
Bijan Bagchi,A. Lahiri,P. K. Roy +2 more
TL;DR: It is shown that the eigenvalue problem of the L operator for the sine-Gordon equation can be put in a supersymmetric form and commented on the connection between the conserved quantities of the Korteweg--de Vries and sine -Gordon systems.
Journal ArticleDOI
Nonuniqueness of the factorization scheme in quantum mechanics
TL;DR: In this paper, the consequences of the nonuniqueness of the factorizability of a quantum mechanical Hamiltonian in one dimension were investigated. But they did not consider the non-uniqueness in terms of the energy spectrum of the harmonic oscillator.
