Some recent results on contact or point supported potentials

Luis M. Nieto, Manuel Gadella, Juan M. Mateos-Guilarte +2

We introduced some contact potentials that can be written as a linear combination of the Dirac delta and its first derivative, the $δ$ - $δ^{'}$ interaction. After a simple general pres…

Hyperspherical $δ - δ^{'}$ potentials

J. M. Munoz-Castaneda, L. M. Nieto, C. Romaniega

The spherically symmetric potential $a δ (r - r_{0}) + b δ^{'} (r - r_{0})$ is generalised for the $d$ -dimensional space as a characterisation of a unique selfadjoint extension of the free Ha…
