In this paper we construct $\mathcal{N}=2$ supersymmetric (SUSY) quantum mechanics over several configurations of Dirac-$\delta$ potentials from one single delta to a Dirac " comb \rq\rq. We show in detail how the building of supersymmetry on potentials with delta interactions placed in two or more points on the real line requires the inclusion of quasi-square wells. Therefore, the basic ingredient of a supersymmetric Hamiltonian containing two or more Dirac-$\delta$s is the singular potential… 

{\cal N}=2 Supersymmetric quantum mechanics of N Lieb-Liniger-Yang bosons on a line

A supersymmetric generalization of the Lieb-Liniger-Yang dynamics governing $N$ massive bosons moving on a line with delta interactions among them at coinciding points is developed. The analysis of

Band spectra of periodic hybrid $$\delta \text {-}\delta '$$ structures

We present a detailed study of a generalised one-dimensional Kronig–Penney model using $$\delta \text {-}\delta '$$ potentials. We analyse the band structure and the density of states in two

Quantum vacuum energies and Casimir forces between partially transparent $\delta$-function plates

In this paper the quantum vacuum energies induced by massive fluctuations of one real scalar field on a configuration of two partially transparent plates are analysed. The physical properties of the

A new simple class of superpotentials in SUSY quantum mechanics

In this work, we introduce the class of quantum mechanics superpotentials W(x) = gε(x)x2n and study in detail the cases n = 0 and 1. The n = 0 superpotential is shown to lead to the known problem of

Self-isospectral periodic potentials and supersymmetric quantum mechanics

We discuss supersymmetric quantum mechanical models with periodic potentials. The important new feature is that it is possible for {ital both} isospectral potentials to support zero modes, in

New solvable and quasi exactly solvable periodic potentials

Using the formalism of supersymmetric quantum mechanics, we obtain a large number of new analytically solvable one-dimensional periodic potentials and study their properties. More specif- ically, the

On two-dimensional superpotentials: from classical Hamilton-Jacobi theory to 2D supersymmetric quantum mechanics

Superpotentials in J V = 2 supersymmetric classical mechanics are no more than the Hamilton characteristic function of the Hamilton-Jacobi theory for the associated purely bosonic dynamical system.
