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…
Study of dynamical supersymmetry breaking for the two dimensional lattice Wess-Zumino model
M. Beccaria, G. F. De Angelis, M. Campostrini +1
A new approach to the study of the transition point in a class of two dimensional Wess-Zumino models is presented. The method is based on the calculation of rigorous lower bounds o…
Phase diagram of the lattice Wess-Zumino model from rigorous lower bounds on the energy
Matteo Beccaria, Massimo Campostrini, Gian Fabrizio De Angelis +1
We study the lattice N=1 Wess-Zumino model in two dimensions and we construct a sequence of exact lower bounds on its ground state energy density , converging to i…
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…
