Topology in QCD with 4 flavours of dynamical fermions
B. Alles, M. D'Elia, A. Di Giacomo
We study the topological properties of full QCD with four flavours of dynamical staggered fermions. In particular the topological susceptibility is measured and the problem of the…
Topological properties of QCD with two dynamical fermions
B. Alles, M. D'Elia, A. Di Giacomo
We investigate the topological susceptibility of the QCD vacuum with two flavours of dynamical staggered fermions on the lattice both at zero and finite temperature. At zero temper…
Confinement in QCD
A. Di Giacomo
The guiding lines of lattice investigations on colour confinement are reviewed, together with recent results.
What we do understand of Colour Confinement
A. Di Giacomo
A review is presented of what we understand of colour confinement in QCD. Lattice formulation provides evidence that QCD vacuum is a dual superconductor: the chromoelectric field o…
Colour confinement and dual superconductivity of the vacuum - II
A. Di Giacomo, B. Lucini, L. Montesi +1
The dual superconductivity of the vacuum in SU(3) gauge theory is investigated by constructing a disorder parameter which signals monopole condensation in various abelian projectio…
Colour confinement and dual superconductivity of the vacuum - I
A. Di Giacomo, B. Lucini, L. Montesi +1
We study dual superconductivity of the ground state of SU(2) gauge theory, in connection with confinement. We do that measuring on the lattice a disorder parameter describing conde…
A dual view of the 3d Heisenberg model and the abelian projection
A. Di Giacomo, D. Martelli, G. Paffuti
The Heisenberg model in 3d is studied from a dual point of view. It is shown that it can have vortex configurations, carrying a conserved charge(U(1) symmetry). Vortices condens in…
