The supersymmetric Ward identities on the lattice
F. Farchioni, A. Feo, T. Galla +5
Supersymmetric (SUSY) Ward identities are considered for the N=1 SU(2) SUSY Yang Mills theory discretized on the lattice with Wilson fermions (gluinos). They are used in order to c…
SUSY Ward identities in 1-loop perturbation theory
Federico Farchioni, Alessandra Feo, Tobias Galla +6
We present preliminary results of a study of the supersymmetric (SUSY) Ward identities (WIs) for the N=1 SU(2) SUSY Yang-Mills theory in the context of one-loop lattice perturbatio…
Lattice supersymmetric Ward identities
F. Farchioni, A. Feo, T. Galla +5
SUSY Ward identities for the N=1 SU(2) SUSY Yang-Mills theory are studied on the lattice in a non-perturbative numerical approach. As a result a determination of the subtracted glu…
Hamiltonian Monte Carlo simulation of the two-dimensional Wess-Zumino model
Matteo Beccaria, Massimo Campostrini, Alessandra Feo
We study a Hamiltonian lattice version of the two-dimensional Wess-Zumino model. Preliminary results obtained by Quantum Monte Carlo with a many-parameter guiding wave function are…
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…
