Spectral Asymptotics of Discrete Schrödinger Operators Under Point Interaction Potentials"
Year: 2025
Type: conference-paper
Abstract: We investigate the one-particle discrete Schrödinger operator with Dirac delta potential on the -dimensional lattice. We show that the operator the operator has a unique eigenvalue and obtain an asymptotics expansion for this eigenvalue as wight of potential approaches the infinity.
