Can degenerate bound states occur in one dimensional quantum mechanics?
Sayan Kar, Rajesh R. Parwani
We point out that bound states, degenerate in energy but differing in parity, may form in one dimensional quantum systems even if the potential is non-singular in any finite domain…

Exact bound states in volcano potentials
Ratna Koley, Sayan Kar
Quantum mechanics in a one--parameter family of volcano potentials is investigated. After a discussion on their construction and classical mechanics, we obtain exact, normalisable…
