| contents | By combining stability analysis of scalar field theories with the Darboux transformation technique, we create models featuring kink-like solutions whose quantum perturbations are all bounded. On the one hand, the stability analysis relates scalar theories with Schrödinger equations, whose solutions serve as quantum perturbation modes. On the other hand, the Darboux transformation allows for constructing new exotic but solvable Schrödinger equations. This framework relates the quantum harmonic oscillator and its rational deformations to exotic scalar theories featuring non-trivial potentials. Depending on the structure of the spectrum of perturbation frequencies, these potentials may have various local maximums, minimums, and inflection points. The stationary solutions take the form of the definite integral over a finite interval of a function times the Gaussian bell distribution, including the Error and the Owen $T$ functions. Such models do not propagate quantum perturbations around the respective vacuums, so zero-point renormalization does not take place. However, Riemann$-ζ$ function regularization allows us to achieve finite one-loop quantum corrections to the classical mass. |
