Eigenvalues of multiterm inverse-fractional-power potentials

Cao Xuan Chuan ; 01 Parvis du Breuil, 92160 Antony, France

Abstract

It is shown that eigenspectra corresponding to various interactions with three- and two-term inverse fractional power are, under certain conditions, analytically tractable either by using the solution of the biconfluent Heun's equation or by using the quasi-exactly solvable sl(2) symmetry approach.

Keywords

inverse fractional power potentials; three and two terms; biconfluent Heun's equation; sl(2) symmetry approach
