Discrete spectrum distribution of the Landau Operator Perturbed by an Expanding Electric Potential
Grigori Rozenblum, Alexander V. Sobolev
Under a perturbation by a decaying electric potential, the Landau Hamiltonian acquires some discrete eigenvalues between the Landau levels. We study the perturbation by an "expandi…

Eigenvalue clusters of the Landau Hamiltonian in the exterior of a compact domain
Alexander Pushnitski, Grigori Rozenblum
We consider the Schrodinger operator with a constant magnetic field in the exterior of a compact domain on the plane. The spectrum of this operator consists of clusters of eigenval…
