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\…

Semi-classical analysis of the Laplace operator with Robin boundary conditions
Rupert L. Frank, Leander Geisinger
We prove a two-term asymptotic expansion of eigenvalue sums of the Laplacian on a bounded domain with Neumann, or more generally, Robin boundary conditions. We formulate and prove…
