On the renormalization of non-polynomial field theories
Andrea Santonocito, Dario Zappala
A class of scalar models with non-polynomial interaction, which naturally admits an analytical resummation of the series of tadpole diagrams is studied in perturbation theory. In p…
Aharonov-Bohm effect for confined matter in lattice gauge theories
Enrico C. Domanti, Paolo Castorina, Dario Zappalà +1
Gauge theories arise in physical systems displaying space-time local symmetries. They provide a powerful description of important realms of physics ranging from fundamental interac…
Lorentz symmetry violating Lifshitz-type field theories
Emiliano Rizza, Dario Zappala
We discuss the ultraviolet sector of 3+1 dimensional Lifshitz-type anisotropic higher derivative scalar, fermion and gauge field theories, with anisotropy exponent z=3 and with exp…
Structural aspects of FRG in quantum tunnelling computations
Alfio Bonanno, Alessandro Codello, Dario Zappala'
We probe both the unidimensional quartic harmonic oscillator and the double well potential through a numerical analysis of the Functional Renormalization Group flow equations trunc…
Ultraviolet properties of Lifshitz-type scalar field theories
Dario Zappala
We consider Lifshitz-type scalar field theories that exhibit anisotropic scaling laws near the ultraviolet fixed point, with explicit breaking of Lorentz symmetry. It is shown that…
On the regularization of Lifshitz-type field theories
Alfio Bonanno, Miok Park, Lesław Rachwał +1
We consider Lifshitz-type scalar theories with explicit breaking of the Lorentz symmetry that, in addition, exhibit anisotropic scaling laws near the ultraviolet fixed point. Using…
