Supersymmetric Yang-Mills quantum mechanics in various dimensions
Jacek Wosiek, Massimo Campostrini
Supersymmetric Yang-Mills quantum mechanics (SYMQM) results from the dimensional reduction of the Yang-Mills field theory in space-time dimensions to a single point in the $D-1…
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…
The large-N expansion of unitary-matrix models
Paolo Rossi, Massimo Campostrini, Ettore Vicari
The general features of the 1/N expansion in statistical mechanics and quantum field theory are briefly reviewed both from the theoretical and from the phenomenological point of vi…
Comment on A. Patrascioiu and E. Seiler's paper ``Nonuniformity of the Expansion for Two-Dimensional Models''
Massimo Campostrini, Paolo Rossi
We remind that the non-uniformity in the temperature of the expansion for dimensionful quantities pointed out in Patrascioiu and Seiler's paper is not only compatible with bu…
