We study and simulate N= 2 supersymmetric Wess–Zumino models in one and two
dimensions. For any choice of the lattice derivative, the theories can be made manifestly …

Lattice versions with restricted supersymmetry of simple (1+ 1)-dimensional supersymmetric
models are numerically studied using a local hamiltonian Monte Carlo method. The pattern …

We consider the two-dimensional N=(2, 2) Wess-Zumino model with a cubic superpotential
at weak and intermediate couplings. Refined algorithms allow for the extraction of reliable …

We study dynamical supersymmetry breaking by nonperturbative lattice techniques in a
class of two-dimensional N= 1 Wess-Zumino models. We work in the Hamiltonian formalism …

The major obstacle to a supersymmetric theory on the lattice is the failure of the Leibniz rule.
We analyze this issue by using the Wess–Zumino model and a general Ginsparg–Wilson …

Starting from a simple discrete model which exhibits a supersymmetric invariance we
construct a local, interacting, two-dimensional Euclidean lattice theory which also admits an …

We analyse supersymmetric models that show supersymmetry breaking in one and two
dimensions using lattice methods. Starting from supersymmetric quantum mechanics, we …

We study the two-dimensional Wess-Zumino model with extended N= 2 supersymmetry on
the lattice. The lattice prescription we choose has the merit of preserving exactly a single …

A lattice formulation of the four dimensional Wess-Zumino model that uses Ginsparg-Wilson
fermions and keeps exact supersymmetry is presented. The supersymmetry transformation …
