Supersymmetric Method for Constructing Quasi-Exactly and Conditionally-Exactly Solvable Potentials
Full text linkUsing supersymmetric quantum mechanics we develop a new method for
constructing quasi-exactly solvable (QES) potentials with two known
eigenstates. This method is extended for constructing conditionally-exactly
solvable potentials (CES). The considered QES potentials at certain values of
parameters become exactly solvable and can be treated as CES ones.Comment: 17 pages, latex, no figure
