Spectral asymmetry on the ball and asymptotics of the asymmetry kernel
A. Kirchberg, K. Kirsten, E. M. Santangelo +1
Let $\ui\di$ be the Dirac operator on a dimensional ball $\mcB$ with radius . We calculate the spectral asymmetry $η(0,\ui\di)$ for D=2 and D=4, when local chiral bag bou…
From the Dirac Operator to Wess-Zumino Models on Spatial Lattices
A. Kirchberg, J. D. Laenge, A. Wipf
We investigate two-dimensional Wess-Zumino models in the continuum and on spatial lattices in detail. We show that a non-antisymmetric lattice derivative not only excludes chiral f…
Extended Supersymmetries and the Dirac Operator
A. Kirchberg, J. D. Laenge, A. Wipf
We consider supersymmetric quantum mechanical systems in arbitrary dimensions on curved spaces with nontrivial gauge fields. The square of the Dirac operator serves as Hamiltonian.…
Algebraic Solution of the Supersymmetric Hydrogen Atom in d Dimensions
A. Kirchberg, J. D. Laenge, P. A. G. Pisani +1
In this paper the N=2 supersymmetric extension of the Schroedinger Hamiltonian with 1/r-potential in arbitrary space-dimensions is constructed. The supersymmetric hydrogen atom adm…
