We first give the solution for the local approximation of a four parameter family of generalized one-dimensional point interactions within the framework of non-relativistic model with three neighboring $\delta$ functions. We also discuss the problem within relativistic (Dirac) framework and give the solution for a three parameter family. It gives a physical interpretation for so-called $\epsilon$ potential. It will be also shown that the scattering properties at high energy substantially differ…

New analytically solvable models of relativistic point interactions

Two new analytically solvable models of relativistic point interactions in one dimension (being natural extensions of the nonrelativistic δ, resp. δ′, interactions) are considered. Their spectral…

Some Aspects of Generalized Contact Interaction in One-Dimensional Quantum Mechanics

A local construction is presented for a one-dimensional contact interaction (e potential) which induces the discontinuity of the wave function while keeping its derivative continuous. By combining…

Four-parameter point-interaction in 1D quantum systems

The author constructs a four-parameter point-interaction for a nonrelativistic particle moving on a line as the limit of a short-range interaction with a range tending toward zero. For particular…

A class of explicitly soluble, local, many‐center Hamiltonians for one‐particle quantum mechanics in two and three dimensions. I

We derive an explicit formula for the resolvent of a class of one‐particle, many‐center, local Hamiltonians. This formula gives, in particular, a full description of a model molecule given by point…

We show that various self-adjoint extensions of the operatorH00=−d2/dx2,D(H00)= =C∞(R{o}) describes a particle moving under additional influence of the generalized Fermi pseudopotential.
