Abstract

PT-symmetric potentials V(x)=x4+\jBx3+Cx2+\jDx+\jF/x+G/x2V({x}) = -{x}^4 +\j B {x}^3 + C {x}^2+\j D {x} +\j F/{x} +G/{x}^2 are quasi-exactly solvable, i.e., a specific choice of a small G=G(QES)=integer/4G=G^{(QES)}= integer/4 is known to lead to wave functions ψ(QES)(x)\psi^{(QES)}(x) in closed form at certain charges F=F(QES)F=F^{(QES)} and energies E=E(QES)E=E^{(QES)}. The existence of an alternative, simpler and non-numerical version of such a construction is announced here in the new dynamical regime of very large G(QES)G^{(QES)} \to \infty.
