| Anomalous Pauli electron states for magnetic fields with tails (1999) | |||||||||
Abstract | |||||||||
| We consider a two-dimensional electron with an anomalous magnetic moment, g>2, interacting with a nonzero magnetic field B perpendicular to the plane which gives rise to a flux F. Recent results about the discrete spectrum of the Pauli operator are extended to fields with the O(r^{-2-\delta}) decay at infinity: we show that if |F| exceeds an integer N, there is at least N+1 bound states. Furthermore, we prove that weakly coupled bound states exist under mild regularity assumptions also in the zero flux case.. Comment: 12 pages, LaTeX2e; the final version, to appear in Lett. Math.
