- Abstract: It is shown that the extensions of exactly-solvable quantum mechanical
problems connected with the replacement of ordinary derivatives by Dunkl ones
and with that of classical orthogonal polynomials by exceptional orthogonal
ones can be easily combined. For such a purpose, the example of the Dunkl
oscillator on the line is considered and three different types of
rationally-extended Dunkl oscillators are constructed. The corresponding
wavefunctions are expressed in terms of exceptional orthogonal generalized
Hermite polynomials, defined in terms of the three different types of
$X_m$-Laguerre exceptional orthogonal polynomials. Furthermore, the extended
Dunkl oscillator Hamiltonians are shown to be expressible in terms of some
extended Dunkl derivatives and some anharmonic oscillator potentials.

This paper presents the first-order supersymmetric rational extension of the quantum anisotropic harmonic oscillator (QAHO) in multiple dimensions, including full-line, half-line, and their combinations.
The exact solutions are in terms of the exceptionals. The rationally extended potentials are isospectral to the conventional QAHOs.

We reformulate the technique of third quantization in a way that explicitly connects all three methods.
We first show that our formulation reveals a fundamental dissipative symmetry present in all quadratic bosonic or fermionic Lindbladians.
For bosons, we then show that the Wigner function and the characteristic function can be thought of as ''wavefunctions'' of the density matrix.
