The Pierre Auger Collaboration

- M. Will, L. Wiencke, +492 authors M. Ziolkowski
- Physics
- 1 June 2013

The Pierre Auger Collaboration has reported evidence for anisotropies in the arrival directions of cosmic rays with energies larger thanEth = 55 EeV. There is a correlation above the isotropic… Expand

Quantum corrections in the group field theory formulation of the Engle-Pereira-Rovelli-Livine and Freidel-Krasnov models

- T. Krajewski, J. Magnen, V. Rivasseau, A. Tanasa, P. Vitale
- Physics
- 30 December 2010

We investigate the group field theory formulation of the Engle-Pereira-Rovelli-Livine/Freidel-Krasnov (EPRL/FK spin-foam models. These models aim at a dynamical, i.e., nontopological formulation of… Expand

Twisting all the way: From classical mechanics to quantum fields

- P. Aschieri, F. Lizzi, P. Vitale
- Physics, Mathematics
- 22 August 2007

We discuss the effects that a noncommutative geometry induced by a Drinfeld twist has on physical theories. We systematically deform all products and symmetries of the theory. We discuss… Expand

Temperature induced phase transitions in four fermion models in curved space-time

- P. Vitale
- Physics
- 9 December 1998

Abstract The large N limit of the Gross-Neveu model is here studied on manifolds with constant curvature, at zero and finite temperature. Using the ζ-function regularization, the phase structure is… Expand

Translation invariance, commutation relations and ultraviolet/infrared mixing

- Salvatore Galluccio, F. Lizzi, P. Vitale
- Physics
- 21 July 2009

We show that the Ultraviolet/Infrared mixing of noncommutative field theories with the Gronewold-Moyal product, whereby some (but not all) ultraviolet divergences become infrared, is a generic… Expand

Quantum Corrections in the Group Field Theory Formulation of the EPRL/FK Models

- T. Krajewski, J. Magnen, V. Rivasseau, A. Tanasa, P. Vitale
- Physics
- 19 July 2010

We investigate the group field theory formulation of the EPRL/FK spin foam models. These models aim at a dynamical, i.e. non-topological formulation of 4D quantum gravity. We introduce a saddle point… Expand

- Physics, Mathematics
- 23 December 2016

In classical information geometry, the metric tensor and a dual pair of connections on the space of probability distributions may be obtained from a potential function.The metric is essentially… Expand

Curing the UV/IR mixing for field theories with translation-invariant $\star$ products

The ultraviolet/infrared (UV/IR) mixing of noncommutative field theories has been recently shown to be a generic feature of translation-invariant associative products. In this paper we propose to… Expand

Jacobi sigma models

- Francesco Bascone, F. Pezzella, P. Vitale
- Physics, Mathematics
- 24 July 2020

We introduce a two-dimensional sigma model associated with a Jacobi manifold. The model is a generalisation of a Poisson sigma model, hence providing a topological open string theory. In the… Expand
