Non-Hermitian Hamiltonians with real and complex eigenvalues: An sl(2,C) approach
B. Bagchi, C. Quesne
Potential algebras are extended from Hermitian to non-Hermitian Hamiltonians and shown to provide an elegant method for studying the transition from real to complex eigenvalues for…

Infinite square well and periodic trajectories in classical mechanics
B. Bagchi, S. Mallik, C. Quesne
We examine the classical problem of an infinite square well by considering Hamilton's equations in one dimension and Hamilton-Jacobi equation for motion in two dimensions. We illus…

Lattice Bosons
Jayprokas Chakrabarti, Asis Basu, Bijon Bagchi
Fermions on the lattice have bosonic excitations generated from the underlying periodic background. These, the lattice bosons, arise near the empty band or when the bands are nearl…
