Beta-function, Renormalons and the Mass Term from Perturbative Wilson Loops
G. Burgio, F. Di Renzo, L. Scorzato +1
Several Wilson loops on several lattice sizes are computed in Perturbation Theory via a stochastic method. Applications include: Renormalons, the Mass Term in Heavy Quark Effective…
Numerical Stochastic Perturbation Theory. Convergence and features of the stochastic process. Computations at fixed (Landau) Gauge
F. Di Renzo, L. Scorzato
Concerning Numerical Stochastic Perturbation Theory, we discuss the convergence of the stochastic process (idea of the proof, features of the limit distribution, rate of convergenc…
Hamiltonian LGT in the complete Fourier analysis basis
G. Burgio, R. De Pietri, H. A. Morales-Tecotl +2
The main problem in the Hamiltonian formulation of Lattice Gauge Theories is the determination of an appropriate basis avoiding the over-completeness arising from Mandelstam relati…
Non-Hermitian tridiagonal random matrices and returns to the origin of a random walk
G. M. Cicuta, M. Contedini, L. Molinari
We study a class of tridiagonal matrix models, the "q-roots of unity" models, which includes the sign () and the clock () models by Feinberg and Zee. We find that th…
The basis of the physical Hilbert space of lattice gauge theories
G. Burgio, R. De Pietri, H. A. Morales-Tecotl +2
Non-linear Fourier analysis on compact groups is used to construct an orthonormal basis of the physical (gauge invariant) Hilbert space of Hamiltonian lattice gauge theories. In pa…
Instanton contributions to Wilson loops with general winding number in two dimensions and the spectral density
A. Bassetto, L. Griguolo, F. Vian
The exact expression for Wilson loop averages winding n times on a closed contour is obtained in two dimensions for pure U(N) Yang-Mills theory and, rather surprisingly, it display…
Non-universality of compact support probability distributions in random matrix theory
G. Akemann, G. M. Cicuta, L. Molinari +1
The two-point resolvent is calculated in the large-n limit for the generalized fixed and bounded trace ensembles. It is shown to disagree with the one of the canonical Gaussian ens…
