Continuum limit for Laplace and Elliptic operators on lattices

Keita Mikami, Shu Nakamura, Yukihide Tadano

Continuum limits of Laplace operators on general lattices are considered, and it is shown that these operators converge to elliptic operators on the Euclidean space in the sense of…

Continuum limit of the lattice quantum graph Hamiltonian

Pavel Exner, Shu Nakamura, Yukihide Tadano

We consider the quantum graph Hamiltonian on the square lattice in Euclidean space, and we show that the spectrum of the Hamiltonian converges to the corresponding Schrödinger oper…

On a continuum limit of discrete Schrödinger operators on square lattice

Shu Nakamura, Yukihide Tadano

The norm resolvent convergence of discrete Schrödinger operators to a continuum Schrödinger operator in the continuum limit is proved under relatively weak assumptions. This result…

Long-range scattering theory for discrete Schrödinger operators on graphene

Yukihide Tadano

We consider a long-range scattering theory for discrete Schrödinger operators on the hexagonal lattice, which describe tight-binding Hamiltonians on the graphene sheet. We construc…

Uniform bounds of discrete Birman-Schwinger operators

Yukihide Tadano, Kouichi Taira

In this note, uniform bounds of the Birman-Schwinger operators in the discrete setting are studied. For uniformly decaying potentials, we obtain the same bound as in the continuous…

Long-range scattering for discrete Schrödinger operators

Yukihide Tadano

In this paper, we define time-independent modifiers to construct a long-range scattering theory for discrete schrödinger operators on the square lattice . We prove th…
