Lattice models with N = 2 supersymmetry
Physical Review Letters 90:12 (2003)
Abstract:
Lattice models with N = 2 supersymmetry are introduced. It is shown that the continuum limit of the simplest of these models is a well known (1 + 1)-dimensional quantum field theory with N = (2,2) superconformal symmetry. The close connections with models of current interest in the study of strongly correlated electrons is noted. Furthermore, it is demonstrated how supersymmetry can be useful in studying their properties.BPS and non-BPS states in a supersymmetric Landau-Ginzburg theory
