Polynomial Structure of the (Open) Topological String Partition Function
M. Alim, J. D. Laenge
In this paper we show that the polynomial structure of the topological string partition function found by Yamaguchi and Yau for the quintic holds for an arbitrary Calabi-Yau manifo…
Supersymmetric Branes in Generic M-Theory Attractor Geometries
S. Ansari, J. D. Laenge, I. Sachs
For a given attractor black hole with generic D6-D4-D2-D0-charges in four dimensions we identify the set of supersymmetric branes, static or stationary in global coordinates, of th…
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…
