Semiclassical eigenvalue estimates for the Pauli operator with strong non-homogeneous magnetic fields. II: Leading order asymptotic estimates. (English) Zbl 0909.47052
Summary: We give the leading order semiclassical asymptotics for the sum of the negative eigenvalues of the Pauli operator (in dimension two and three) with a strong non-homogeneous magnetic field. As in [E. H. Lieb, J. P. Solovej and J. Yngvason, Commun. Math. Phys. 161, 77-124 (1994; Zbl 0807.47058)] for homogeneous field, this result can be used to prove that the magnetic Thomas-Fermi theory gives the leading order ground state energy of large atoms. We develop a new localization scheme well suited to the anisotropic character of the strong magnetic field. We also use the basic Lieb-Thirring estimate obtained in our companion paper [Part I, preprint 1996].
