Dynamical supersymmetry breaking and phase diagram of the lattice Wess-Zumino model
Matteo Beccaria, Gian Fabrizio De Angelis, Massimo Campostrini +1
We study dynamical supersymmetry breaking and the transition point by non-perturbative lattice techniques in a class of two-dimensional N=1 Wess-Zumino model. The method is based o…

An exact representation of the fermion dynamics in terms of Poisson processes
Matteo Beccaria, Carlo Presilla, Gian Fabrizio De Angelis +1
We present a simple derivation of a Feynman-Kac type formula to study fermionic systems. In this approach the real time or the imaginary time dynamics is expressed in terms of the…
