Spectral shift and multiplicity of the first eigenvalue of the magnetic Schrödinger operator in two dimensions

László Erdős (2002)

Annales de l’institut Fourier

Similarity:

We show that the lowest eigenvalue of the magnetic Schrödinger operator on a line bundle over a compact Riemann surface M is bounded by the L 1 -norm of the magnetic field B . This implies a similar bound on the multiplicity of the ground state. An example shows that this degeneracy can indeed be comparable with M | B | even in case of the trivial bundle.

A Lieb-Thirring bound for a magnetic Pauli Hamiltonian (II).

Luca Bugliaro, Charles L. Fefferman, Gian Michele Graf (1999)

Revista Matemática Iberoamericana

Similarity:

We establish a Lieb-Thirring type estimate for Pauli Hamiltonians with non-homogeneous magnetic fields. Besides of depending on the size of the field, the bound also takes into account the size of the field gradient. We then apply the inequality to prove stability of non-relativistic quantum mechanical matter coupled to the quantized ultraviolet-cutoff electromagnetic field for arbitrary values of the fine structure constant.

Asymptotic distribution of negative eigenvalues for two dimensional Pauli operators with nonconstant magnetic fields

Akira Iwatsuka, Hideo Tamura (1998)

Annales de l'institut Fourier

Similarity:

This article studies the asymptotic behavior of the number N ( λ ) of the negative eigenvalues < - λ as λ + 0 of the two dimensional Pauli operators with electric potential V ( x ) decaying at and with nonconstant magnetic field b ( x ) , which is assumed to be bounded or to decay at . In particular, it is shown that N ( λ ) = ( 1 / 2 π ) V ( x ) > λ b ( x ) d x ( 1 + o ( 1 ) ) , when V ( x ) decays faster than b ( x ) under some additional conditions.
