Large-N phase transition in lattice 2-d principal chiral models

M. Campostrini, P. Rossi, E. Vicari

We investigate the large-N critical behavior of 2-d lattice chiral models by Monte Carlo simulations of U(N) and SU(N) groups at large N. Numerical results confirm strong coupling…

Strong coupling analysis of the large-N 2-d lattice chiral models

M. Campostrini, P. Rossi, E. Vicari

Two dimensional large-N chiral models on the square and honeycomb lattices are investigated by a strong coupling analysis. Strong coupling expansion turns out to be predictive for…

Running coupling constant and correlation length from Wilson loops

Massimo Campostrini, Paolo Rossi, Ettore Vicari

We consider a definition of the QCD running coupling constant $α (μ)$ related to Wilson loops of size $r \times t$ with arbitrary fixed $t / r$ . The schemes defined by these couplings…

Master Wilson loop operators in large-N lattice QCD $_{2}$

P. Rossi, E. Vicari

An explicit solution is found for the most general independent correlation functions in lattice QCD $_{2}$ with Wilson action. The large- $N$ limit of these correlations may be used to…

On $T$ dependence of the static potential $V (T; R)$ in a finite volume

G. ~Cella, V. K. ~Mitrjushkin, A. ~Viceré

We study the dependence on $T$ of the static potential $V (T; R)$ defined from Wilson loops and from Polyakov loop correlators on a finite lattice. For this study we employ a…

New Method for the Extrapolation of Finite-Size Data to Infinite Volume

Sergio Caracciolo, Robert G. Edwards, Sabino J. Ferreira +2

We present a simple and powerful method for extrapolating finite-volume Monte Carlo data to infinite volume, based on finite-size-scaling theory. We discuss carefully its systemati…

L. Del Debbio, A. Di Giacomo, G. Paffuti +1

We study the behaviour of a suitably defined disorder parameter, showing for the first time monopole condenssation in the ground state of QCD.

Detecting Dual Superconductivity in the Ground State of Gauge Theory

L. Del Debbio A. Di Giacomo, G. Paffuti

We explicitly construct a monopole creation operator: its vacuum expectation value is an order parameter for dual superconductivity, in that, if different from zero, it signals a s…
