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…
An Improved Upper Bound for the Ground State Energy of Fermion Lattice Models
Matteo Beccaria
We present an improved upper bound for the ground state energy of lattice fermion models with sign problem. The bound can be computed by numerical simulation of a recently proposed…
Adaptive Optimization of Wave Functions for Fermion Lattice Models
Matteo Beccaria, Antonio Moro
We present a simulation algorithm for Hamiltonian fermion lattice models. A guiding trial wave function is adaptively optimized during Monte Carlo evolution. We apply the method to…
