Quasi-exactly solvable quartic: elementary integrals and asymptotics
We study elementary eigenfunctions y = peh of operators L(y) = y+Py, where p, h and P are polynomials in one variable. For the case when h is an odd cubic polynomial, we found an interesting identity which is used to describe the spectral locus. We also establish some asymptotic properties of the QES spectral locus.

متن کاملSupersymmetric Method for Constructing Quasi-Exactly and Conditionally-Exactly Solvable Potentials
Using 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.
متن کاملQuasi-exact minus-quartic oscillators in strong-core regime
PT −symmetric potentials V (x) = −x + iB x + C x + iDx + iF/x + G/x are quasi-exactly solvable, i.e., a specific choice of a small G = G = integer/4 is known to lead to wave functions ψ(x) in closed form at certain charges F = F (QES) and energies E = E. The existence of an alternative, simpler and non-numerical version of such a construction is announced here in the new dynamical regime of ver...
متن کاملQuasi-exact solvable models based on special functions
We suggest a systematic method of extension of quasi-exactly solvable (QES) systems. We construct finite-dimensional subspaces on the basis of special functions (hypergeometric, Airy, Bessel ones) invariant with respect to the action of differential operators of the second order with polynomial coefficients. As a example of physical applications, we show that the known two-photon Rabi Hamiltoni...
