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…
Adaptive Optimization of Wave Functions for Lattice Field Models
Matteo Beccaria, Massimo Campostrini, Alessandra Feo
The accuracy of Green Function Monte Carlo (GFMC) simulations can be greatly improved by a clever choice of the approximate ground state wave function that controls configuration s…
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…
