Small Mass Expansion of Functional Determinants on the Generalized Cone
Guglielmo Fucci, Klaus Kirsten
In this paper we compute the small mass expansion for the functional determinant of a scalar Laplacian defined on the bounded, generalized cone. In the framework of zeta function r…
On the Gravitationally Induced Schwinger Mechanism
Guglielmo Fucci, Ivan G. Avramidi
In this paper we will present very recent results obtained in the ambit of quantum electrodynamics in curved spacetime. We utilize a newly developed non-perturbative heat kernel as…
Non-Perturbative One-Loop Effective Action for Electrodynamics in Curved Spacetime
Guglielmo Fucci
In this paper we explicitly evaluate the one-loop effective action in four dimensions for scalar and spinor fields under the influence of a strong, covariantly constant, magnetic f…
Non-Perturbative Aspects of Quantum Electrodynamics on Curved Space and Investigations in Matrix Gravity
Guglielmo Fucci
In the first part of this Dissertation, we study non-perturbative aspects of quantum electrodynamics on Riemannian manifolds by using heat kernel asymptotic expansion techniques. H…
Low-Energy Effective Action in Non-Perturbative Electrodynamics in Curved Spacetime
Ivan G. Avramidi, Guglielmo Fucci
We study the heat kernel for the Laplace type partial differential operator acting on smooth sections of a complex spin-tensor bundle over a generic -dimensional Riemannian mani…
