One-loop conformal anomaly in an implicit momentum space regularization framework
A. R. Vieira, J. C. C. Felipe, G. Gazzola +1
In this paper we consider matter fields in a gravitational background in order to compute the breaking of the conformal current at one-loop order. Standard perturbative calculation…
Conductivity of Coulomb interacting massless Dirac particles in graphene: Regularization-dependent parameters and symmetry constraints
G. Gazzola, A. L. Cherchiglia, L. A. Cabral +2
We compute the Coulomb correction to the a. c. conductivity of interacting massless Dirac particles in graphene in the collisionless limit using the polarization tens…
QED with minimal and nonminimal couplings: on the quantum generation of Lorentz violating terms in the pure photon sector
G. Gazzola, H. G. Fargnoli, A. P. Baêta Scarpelli +2
We consider an effective model formed by usual QED (minimal coupling) with the addition of a nonminimal Lorentz violating interaction (proportional to a fixed 4-vector ) which…
On the Casimir energy for a massive quantum scalar field and the Cosmological constant
G. Gazzola, M. C. Nemes, W. F. Wreszinski
We present a rigorous, regularization independent local quantum field theoretic treatment of the Casimir effect for a quantum scalar field of mass which yields closed form…
