Decorrelating the topology in full QCD
G. Boyd, B. Allés, M. D'Elia +2
We investigate the performance of the hybrid Monte Carlo algorithm in updating non-trivial global topological structures. We find that the hybrid Monte Carlo algorithm has serious…
Hybrid Monte Carlo and topological modes of full QCD
B. Allés, G. Boyd, M. D'Elia +2
We investigate the performance of the hybrid Monte Carlo algorithm, the standard algorithm used for lattice QCD simulations involving fermions, in updating non-trivial global topol…
Condensation of vortices in the X-Y model in 3d: a disorder parameter
G. Di Cecio, A. Di Giacomo, G. Paffuti +1
A disorder parameter is constructed which signals the condensation of vortices. The construction is tested by numerical simulations on lattice.
Field strength correlators in QCD at zero and non-zero temperature
Adriano Di Giacomo, Enrico Meggiolaro, Haralambos Panagopoulos
We study, by numerical simulations on a lattice, the behaviour of the gauge--invariant field strength correlators in QCD both at zero temperature, down to a distance of 0.1 fm, and…
Topological susceptibility through the deconfining phase transition
B. Alles, M. D'Elia, A. Di Giacomo
We present a measurement of the topological susceptibility in SU(3) Yang-Mills theory through the deconfinement phase transition. An improved operator is used for the topological c…
Topological susceptibility at zero and finite in SU(3) Yang-Mills theory
B. Allés, M. D'Elia, A. Di Giacomo
We determine the topological susceptibility at T=0 in pure SU(3) gauge theory and its behaviour at finite across the deconfining transition. We use an improved topological…
Gauge--invariant field correlators in QCD at finite temperature
Adriano Di Giacomo, Enrico Meggiolaro, Haralambos Panagopoulos
We study by numerical simulations on a lattice the behaviour of the gauge--invariant two--point correlation functions of the gauge field strengths across the deconfinement phase tr…
