On the optimization of the principal eigenvalue for single-centre point-interaction operators in a bounded region
Pavel Exner, Andrea Mantile
We investigate relations between spectral properties of a single-centre point-interaction Hamiltonian describing a particle confined to a bounded domain $Ω\subset\mathbb{R}^{d},\:…

Point Interaction Hamiltonians in Bounded Domains
Ph. Blanchard, R. Figari, A. Mantile
Making use of recent techniques in the theory of selfadjoint extensions of symmetric operators, we characterize the class of point interaction Hamiltonians in a 3-D bounded domain…
