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 Hamiltonian. For this extension of the Dirac delta, the sp

We consider the interaction pressure acting on the surface of a dielectric sphere enclosed within a magnetodielectric cavity. We determine the sign of this quantity regardless of the geometry of the cavity for systems at thermal equilibrium, extendin

We study the vacuum interaction of a scalar field and two concentric spheres defined by a singular potential on their surfaces. The potential is a linear combination of the Dirac $\ensuremath{\delta}$ and its derivative. The presence of the delta pri

We extend our previous work on the electromagnetic Casimir-Lifshitz interaction between two bodies when one is contained within the other. We focus on the fluctuation induced pressure acting on the cavity wall, which is a

We study a non-relativistic particle subject to a three-dimensional spherical potential consisting of a finite well and a radial $\delta$-$\delta'$ contact interaction at the well edge. This contact potential is defined by appropriate matching condit

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 presentation in one dimension, we briefly discuss a one dimensional period

[EN] Solutions of the one-dimensional Schrödinger equation are found when point interactions of the type aδ(x − q) + bδ'(x − q) are placed either in a couple of points or in a regular lattice. The results obtained in the present study are a fi
