Integration of Grassmann variables over invariant functions on flat superspaces
Mario Kieburg, Heiner Kohler, Thomas Guhr
We study integration over functions on superspaces. These functions are invariant under a transformation which maps the whole superspace onto the part of the superspace which only…
Exact diagonalisation of 1-d interacting spinless Fermions
Heiner Kohler
We acquire a method of constructing an infinite set of exact eigenfunctions of 1--d interacting spinless Fermionic systems. Creation and annihilation operators for the interacting…
Supersymmetric Extensions of Calogero--Moser--Sutherland like Models: Construction and Some Solutions
Heiner Kohler, Thomas Guhr
We introduce a new class of models for interacting particles. Our construction is based on Jacobians for the radial coordinates on certain superspaces. The resulting models contain…
Supersymmetry and Models for Two Kinds of Interacting Particles
Thomas Guhr, Heiner Kohler
We show that Calogero-Sutherland models for interacting particles have a natural supersymmetric extension. For the construction, we use Jacobians which appear in certain superspace…
The k-Point Random Matrix Kernels Obtained from One-Point Supermatrix Models
Johan Groenqvist, Thomas Guhr, Heiner Kohler
The k-point correlation functions of the Gaussian Random Matrix Ensembles are certain determinants of functions which depend on only two arguments. They are referred to as kernels,…
Derivation of the Supersymmetric Harish--Chandra Integral for UOSp(k_1/2k_2)
Thomas Guhr, Heiner Kohler
The previous supersymmetric generalization of the unitary Harish--Chandra integral prompted the conjecture that the Harish--Chandra formula should extend to all classical supergrou…
