Wigner-Husimi phase-space structure of quasi-exactly solvable sextic potential

Angelina N. Mendoza Tavera, Adrian M. Escobar Ruiz, Robin P. Sagar

In this study, we compare the Wigner function $W$ , its modulus, and the Husimi distribution $H$ in a one-dimensional quantum system exhibiting a transition from a single-well to a…

Entropic characterization of Tunneling and State Pairing in a Quasi-Exactly Solvable Sextic Potential

Angelina N. Mendoza Tavera, Adrian M. Escobar Ruiz, Robin P. Sagar

We analyze the (de)localization properties of a quasi-exactly solvable (QES) sextic potential $V_{QES} (x) = \frac{1}{2} (x^{6} + 2 x^{4} - 2 (2 λ + 1) x^{2})$ as a function of the tunab…
