A new approach to the two-dimensional -model with a topological charge
C. Torrero, O. Borisenko, V. Kushnir +2
Based on character decomposition, a dual transformation is introduced leading to two formulations of the theory which should allow for a removal/softening of the sign problem in th…
Monte Carlo study of the two-dimensional site-diluted dipolar Ising model
J. J. Alonso, B. Allés
By tempered Monte Carlo simulations, we study 2D site-diluted dipolar Ising systems. Dipoles are randomly placed on a fraction x of all L^2 sites in a square lattice, and point alo…
Numerical study of the mass spectrum in the 2D O(3) sigma model with a theta term
B. Alles, A. Papa
It has been conjectured that the mass spectrum of the O(3) non-linear sigma model with a theta term in 2 dimensions may possess an excited state, which decays when theta is lowered…
Reply to A. Patrascioiu's and E. Seiler's comment on our paper "The two-phase issue in the O(n) non-linear sigma-model: a Monte Carlo study"
B. Alles, A. Buonanno, G. Cella
We reply to a comment by A. Patrascioiu and E. Seiler appeared in hep-lat/9608138 on our paper hep-lat/9608002.
Renormalization and topological susceptibility on the lattice: SU(2) Yang-Mills theory
Bartomeu Alles, Massimo Campostrini, Adriano Di Giacomo +2
The renormalization functions involved in the determination of the topological susceptibility in the SU(2) lattice gauge theory are extracted by direct measurements, without relyin…
