Diffraction and Scattering Theory of the Aharonov-Bohm Hamiltonian
PublicDownloadable Content
Download PDFThis dissertation provides an introduction to the diffraction and scattering theory for the Aharonov--Bohm Hamiltonian with one or multiple poles on $\mathbf{R}^2$. It shows the propagation of diffractive singularities of the wave equation with the magnetic Hamiltonians with singular vector potential, which is related to the so-called Aharonov--Bohm effect. Based on the diffractive theorem, a Duistermaat--Guillemin type trace formula is given and singularities of the wave trace are computed. Then a Vainberg parametrix method is used to prove a resolvent estimate for the Aharonov--Bohm Hamiltonian with multiple poles. Finally, some applications of these results are given; in particular, scattering resonances generated by diffractions between the multiple singular vector potentials are discussed.
