QCD, monopoles on the Lattice and gauge invariance
C. Bonati, M. D'Elia, A. Di Giacomo
The number and the location of the monopoles observed on the lattice in QCD configurations happens to depend strongly on the choice of the gauge used to expose them, in contrast to…
The Roberge-Weiss endpoint in N_f = 2 QCD
Claudio Bonati, Guido Cossu, Massimo D'Elia +1
We present the results of extensive simulations regarding the critical behavior at the endpoint of the Roberge-Weiss transition for N_f = 2 QCD. We confirm early evidence, presente…
Non abelian Bianchi identities, monopoles and gauge invariance
Claudio Bonati, Massimo D'Elia, Adriano Di Giacomo +2
A direct connection is proved between the Non-Abelian Bianchi Identities and the Abelian Bianchi identities for the 't Hooft tensor in a generic gauge; the existence of a magnetic…
Staggered fermions simulations on GPUs
Claudio Bonati, Guido Cossu, Massimo D'Elia +1
We present our implementation of the RHMC algorithm for staggered fermions on Graphics Processing Units using the NVIDIA CUDA programming language. While previous studies exclusive…
Toward a well defined monopole creation operator
Claudio Bonati, Guido Cossu, Massimo D'Elia +1
The lattice implementation of monopole creation operator proves to have problems related to bulk transitions that can possibly affect the interpretation of its mean value as an ord…
The three-dimensional, three state Potts model in a negative external field
Claudio Bonati, Massimo D'Elia
We investigate the critical behaviour of the three-dimensional, three state Potts model in presence of a negative external field h, i.e. disfavouring one of the three states. A gen…
