A short proof of Weyl's law for fractional differential operators
Leander Geisinger
We study spectral asymptotics for a large class of differential operators on an open subset of with finite volume. This class includes the Dirichlet Laplacian, the fractiona…

Convergence of the density of states and delocalization of eigenvectors on random regular graphs
Leander Geisinger
Consider a random regular graph of fixed degree with vertices. We study spectral properties of the adjacency matrix and of random Schrödinger operators on such a graph as $…

The ground state energy of a polaron in a strong magnetic field
Rupert L. Frank, Leander Geisinger
We show that the ground state of a polaron in a homogeneous magnetic field and its energy are described by an effective one-dimensional minimization problem in the limit $B\to\…
