[EN] We investigate a special class of the PT-symmetric quantum models being perfectly invisible zero-gap systems with a unique bound state at the very edge of continuous spectrum of scattering states. The family includes the PT-regularized two parti

[EN]The effects induced by the quantum vacuum fluctuations of one massless real scalar field on a configuration of two partially transparent plates are investigated. The physical properties of the infinitely thin plates are simulated by means of Dira

[EN] In this paper we construct N = 2 supersymmetric (SUSY) quantum mechanics over several configurations of Dirac- δ potentials from one single delta to a Dirac “comb ”. We show in detail how the building of supersymmetry on potentials with del

[EN] It is shown that the Confluent Heun Equation (CHEq) reduces for certain conditions of the parameters to a particular class of Quasi-Exactly Solvable models, associated with the Lie algebra $sl (2,{\mathbb R})$. As a consequence it is possible to
