Large expansion of Wilson loops in the Gross-Witten-Wadia matrix model
Eleonora Alfinito, Matteo Beccaria
We study the large expansion of winding Wilson loops in the off-critical regime of the Gross-Witten-Wadia (GWW) unitary matrix model. These have been recently considered in arX…
Time-reversal violation as loop-antiloop symmetry breaking: the Bessel equation, group contraction and dissipation
Eleonora Alfinito, Giuseppe Vitiello
We show that the Bessel equation can be cast, by means of suitable transformations, into a system of two damped/amplified parametric oscillator equations. The relation with the gro…
Double Universe
E. Alfinito, R. Manka, G. Vitiello
We discuss the canonical quantization of non-unitary time evolution in inflating Universe. We consider gravitational wave modes in the FRW metrics in a de Sitter phase and show tha…
A class of nonlinear wave equations containing the continuous Toda case
E. Alfinito, M. S. Causo, G. Profilo +1
We consider a nonlinear field equation which can be derived from a binomial lattice as a continuous limit. This equation, containing a perturbative friction-like term and a free pa…
The symmetry structure of the heavenly equation
E. Alfinito, G. Soliani, L. Solombrino
We show that excitations of physical interest of the heavenly equation are generated by symmetry operators which yields two reduced equations with different characteristics. One eq…
