Following up on recent work by Caron-Huot et al. we consider a generalization of the old Lovelace-Shapiro model as a toy model for Pi-Pi scattering satisfying (most of) the properties expected to hold in ('t Hooft's) large-N limit of massless QCD. In

Perturbation of Hydrogen Degenerate Levels and SO(4)

Autor: Enrico Onofri

Publikováno v: Journal of Modern Physics. :1051-1054

We present a short note about the perturbative correction to Rydberg energies under a perturbation cosθ/rμ and discuss the role of SO(4) symmetry.

SPLITTING LANDAU LEVELS ON THE 2D TORUS BY PERIODIC PERTURBATIONS

Autor: Enrico Onofri

Publikováno v: International Journal of Modern Physics C. 19:1753-1761

We study the spectrum of the Schroedinger operator for a particle constrained on a two-dimensional flat torus under the combined action of a transverse magnetic field and a conservative force. A numerical method is presented which allows to compute t

Exact solution of BFKL equation in jet-physics

Autor: Giuseppe Marchesini, Enrico Onofri

It has been recently found that the heavy quark-antiquark QQbar pair multiplicity, in certain phase space region (QQbar at short distance, soft and with small velocity), satisfies an evolution equation formally similar to the BFKL equation for the hi

Landau levels have represented a very rich field of research, which has gained widespread attention after their application to the quantum Hall effect. In a particular gauge, the holomorphic gauge, they give a physical implementation of Bargmann's Hi

Infrared renormalons and finite volume

Autor: Giuseppe Marchesini, F. DiRenzo, Enrico Onofri

Publikováno v: Nuclear Physics B. 497:435-442

We analyze the perturbative expansion of a condensate in the O(N) non-linear sigma model for large N on a two dimensional finite lattice. On an infinite volume this expansion is affected by an infrared renormalon. We extrapolate this analysis to the

Renormalons from eight-loop expansion of the gluon condensate in lattice gauge theory

Autor: Giuseppe Marchesini, Enrico Onofri, F. Di Renzo

Publikováno v: Nuclear Physics B. 457:202-216

We use a numerical method to obtain the weak coupling perturbative coefficients of local operators with lattice regularization. Such a method allows us to extend the perturbative expansions obtained so far by analytical Feynman diagrams calculations.

Physical Review E : Statistical, Nonlinear, and Soft Matter Physics, 2012, 85 (1, 2), pp.16203. ⟨10.1103/PhysRevE.85.016203⟩

A system of active colloidal particles driven by harmonic potentials to oscillate about the vertices of a regular polygon, with hydrodynamic coupling between all particles, is described by a piece-wise linear model which exhibits various patterns of

Four-loop result in SU(3) lattice gauge theory by a stochastic method: lattice correction to the condensate

Autor: F. Di Renzo, P. Marenzoni, Enrico Onofri, Giuseppe Marchesini

Publikováno v: Nuclear Physics B. 426:675-685

We describe a stochastic technique which allows one to compute numerically the coefficients of the weak coupling perturbative expansion of any observable in Lattice Gauge Theory. The idea is to insert the exponential representation of the link variab
