Quasi-Exact Solvability of Symmetrized Sextic Oscillators and Analyticity of the Related Quotient Polynomials

Authors: Spiros Konstantogiannis

Quasi-exactly solvable symmetrized sextic oscillators have been proposed and studied by Quesne, who categorized them based on the parity – natural or unnatural – of their known eigenfunction [2]. Herein, we examine the quasi-exact solvability of symmetrized sextic oscillators using a quotient-polynomial approach [3, 4, 5], which, in this case, opens up the possibility to construct non-analytic sextic oscillators from analytic quotient polynomials, and thus to distinguish the oscillators resulting from analytic quotient polynomials from those resulting from non-analytic quotient polynomials. We analyze the cases n=0 and n=1, and we show that the results are in agreement with those of Quesne [2]. In the case n=2, we construct sextic oscillators using only analytic quotient polynomials, and focusing on the non-analytic oscillators whose known eigenfunction is of unnatural parity, we register a relation between the coefficients of the two non-analytic terms of the exponential polynomial, which then we generalize to the higher cases n=3 and n=4, to construct new non-analytic sextic oscillators whose known eigenfunction is of unnatural parity.
