Photon Scattering by an Electric Field in Noncommutative Spacetime
Daniela D'Ascanio, Pablo Pisani, Ulises Wainstein Haimovichi
As is known, the existence of a small noncommutativity between coordinates would generate nonlocal self-interactions in the electromagnetic theory. To explore some consequences of…
Quantum Field Theory on spherical space forms
Daniela D'Ascanio
One of the fundamental questions in Quantum Field Theory regards the determination of a measure of the degrees of freedom of theories that is consistent with the Renormalization Gr…
Searching for a -function on the three-dimensional sphere
C. G. Beneventano, I. Cavero-Peláez, D. D'Ascanio +1
We present a detailed analytic study on the three-dimensional sphere of the most popular candidates for -functions, both for Dirac and scalar free massive fields. We discuss to…
Renormalization on noncommutative torus
D. D'Ascanio, P. Pisani, D. V. Vassilevich
We study a self-interacting scalar theory on the -dimensional noncommutative torus. We determine, for the particular cases and , the counterterms required by on…
Noncommutative U(1) gauge theory from a worldline perspective
Naser Ahmadiniaz, Olindo Corradini, Daniela D'Ascanio +2
We study pure noncommutative U(1) gauge theory representing its one-loop effective action in terms of a phase space worldline path integral. We write the quadratic action using the…
Topological Entropy and Renormalization Group flow in 3-dimensional spherical spaces
M. Asorey, C. G. Beneventano, I. Cavero-Peláez +2
We analyze the renormalization group (RG) flow of the temperature independent term of the entropy in the high temperature limit β/a<<1 of a massive field theory in 3-dimensional sp…
Thermodynamics of conformal fields in topologically non-trivial space-time backgrounds
M. Asorey, C. G. Beneventano, D. D'Ascanio +1
We analyze the finite temperature behaviour of massless conformally coupled scalar fields in homogeneous lens spaces . High and low temperature expansions are ex…
