The wave trace and resonances of the magnetic Hamiltonian with singular vector potentials
Abstract
We study leading order singularities of the wave trace of the Aharonov--Bohm Hamiltonian on R2 with multiple solenoids under a generic assumption that no three solenoids are collinear. Then we apply our formula to get a lower bound of scattering resonances in a logarithmic neighborhood near the real axis.
