A conditionally integrable bi-confluent Heun potential involving inverse square root and centrifugal barrier terms
T. A. Ishkhanyan, V. P. Krainov, A. M. Ishkhanyan
We present a conditionally integrable potential, belonging to the bi-confluent Heun class, for which the Schrödinger equation is solved in terms of the confluent hypergeometric fun…

A periodic level-crossing two-state model of a general Heun class
G. Saget, A. M. Ishkhanyan, C. Leroy +1
We present a specific constant-amplitude periodic level-crossing model of the semi-classical quantum time-dependent two-state problem that belongs to a general Heun class of field…
