n Distinguishable Particles on the Real Line interacting via Two Body Delta Potentials

This paper studies a system of $n \in \mathbb{N}: \, n \geq 2$ non-relativistic, spinless quantum particles moving on the real line and interacting via a two-body delta potential. The Hamiltonian of such a system is proved to be affiliated to the resolvent algebra of the case, $\mathcal{R}\left( \mathbb{R}^{2n},σ\right)$; it is further shown the existence of a $\text{C}^{\ast}-$dynamical system and of a subalgebra $π_S\left( \mathfrak{S}_0 \right)^{-1} \subset \mathcal{R}\left( \mathbb{R}^{2n},σ\right)$, stable under time evolution, where $π_S$ is the Schr{ö}dinger representation of the algebra.

One Dimensional Point Interactions and the Resolvent Algebra -- Simple Remarks

This paper shows that the resolvent algebra $\mathcal{R}\left( \mathbb{R}^2,σ\right)$ can accommodate dynamics induced by self-adjoint Hamiltonians on $L^2\left( \mathbb{R} \right)$ describing a single non-relativistic spinless particle undergoing one up to countably many different fixed point interactions located on the real line.
