Testing the heating method with perturbation theory
B. Alles, M. Beccaria, F. Farchioni
The renormalization constants present in the lattice evaluation of the topological susceptibility can be non-perturbatively calculated by using the so-called heating method. We tes…

The 2-dimensional non-linear sigma-model on a random latice
B. Alles, M. Beccaria
The O(n) non-linear -model is simulated on 2-dimensional regular and random lattices. We use two different levels of randomness in the construction of the random lattices and gi…
