Twisted supersymmetric sigma model on the lattice
Simon Catterall, Sofiane Ghadab
In this paper we conduct a numerical study of the supersymmetric O(3) non-linear sigma model. The lattice formulation we employ was derived in \cite{sigma1} and corresponds to a di…

Lattice Study of the O(3) Supersymmetric Sigma Model
Sofiane Ghadab
We present preliminary numerical results from a lattice study of the two-dimensional O(3) non-linear sigma model. In the continuum this model possesses N=2 supersymmetry. The latti…

Lattice Sigma Models with Exact Supersymmetry
Simon Catterall, Sofiane Ghadab
We show how to construct lattice sigma models in one, two and four dimensions which exhibit an exact fermionic symmetry. These models are discretized and {\it twisted} versions of…
