@article{Kan2013SimpleMI, title={Simple models in supersymmetric quantum mechanics on a graph}, author={Nahomi Kan and Koichiro Kobayashi and Kiyoshi Shiraishi}, journal={Journal of Physics A: Mathematical and Theoretical}, year={2013}, volume={46} }

We study some types of dimensionally-deconstructed models for supersymmetric (Euclidean) quantum mechanics, or zero-dimensional field theory. In these models, we assign bosonic and fermionic variables to vertices and the edges of a graph. We investigate a discrete version of the Gaussian model and the Wess–Zumino-type model on a graph. The topological index as a multiple integral is discussed on these models. In addition, we propose simple examples of supersymmetric extensions of the Lee–Wick…
