Monte-Carlo simulation of the chiral Gross-Neveu model
Tomasz Korzec, Francesco Knechtli, Ulli Wolff +1
We investigate the two flavor chiral Gross-Neveu model in the Schroedinger functional on the lattice. The procedure necessary to recover chiral symmetry in the continuum limit of t…
Towards a non-perturbative computation of the RGI strange quark mass with two dynamical flavors
Michele Della Morte, Roland Hoffmann, Francesco Knechtli +4
The non-perturbative running of the quark mass in the Schroedinger functional scheme is computed over a large energy range (covering scales differing by two orders of magnitude). T…
Gauge theories on a five-dimensional orbifold
Francesco Knechtli, Burkhard Bunk, Nikos Irges
We present a construction of non-Abelian gauge theories on the R^4 x S^1/Z_2 orbifold. We show that no divergent boundary mass term for the Higgs field, identified with some of the…
Cutoff effects in the O(N) sigma model at large N
Ulli Wolff, Francesco Knechtli, Bjoern Leder +1
The computation of the step scaling function for the finite size mass-gap in the O(N) sigma model at large N is reviewed. Practically exact nonperturbative results become available…
Two Flavors of Staggered Fermions with Smeared Links
Anna Hasenfratz, Francesco Knechtli
Staggered fermions with smeared links can have greatly improved chiral properties. In a recent paper we introduced a simple and effective method to simulate four flavors of stagger…
Four Flavor Finite Temperature Phase Transition with HYP Action: Where is the First Order Phase Transition Line?
A. Hasenfratz, F. Knechtli
We study the finite temperature phase transition of four flavor staggered fermions with hypercubic fat link actions on N_t=4 and N_t=6 temporal lattices. Our fat links are construc…
