Double Quantization
Giulia Gubitosi, Fedele Lizzi, José Javier Relancio +1
In a quantum gravity theory, it is expected that the classical notion of spacetime disappears, leading to a quantum structure with new properties. A possible way to take into accou…
Four-dimensional noncommutative deformations of gauge theory and bootstrap
Maxim Kurkov, Patrizia Vitale
We construct a family of four-dimensional noncommutative deformations of gauge theory following a general scheme, recently proposed in JHEP 08 (2020) 041 for a class of coor…
Gribov horizon in Noncommutative QED
Ozório Holanda, Marcelo S. Guimaraes, Luigi Rosa +1
It is known that Noncommutative QED (NCQED) exhibits Gribov ambiguities in the Landau gauge. These ambiguities are related to zero modes of the Faddeev-Popov operator and arise in…
A Simple Model of Double Dynamics on Lie Groups
Patrizia Vitale
We study the dynamics of the rigid rotator on the group manifold of SU(2) as an instance of dynamics on Lie groups together with a dual model whose carrier space is the Borel group…
Topological and dynamical aspects of Jacobi sigma models
Francesco Bascone, Franco Pezzella, Patrizia Vitale
The geometric properties of sigma models with target space a Jacobi manifold are investigated. In their basic formulation, these are topological field theories - recently introduce…
Time Discretization From Noncommutativity
Fedele Lizzi, Patrizia Vitale
We show that a particular noncommutative geometry, sometimes called angular or -Minkowski, requires that the spectrum of time be discrete. In this noncommutative space the time…
