Pair creation in weak gravity and gauge backgrounds: spinning fields and binary stars
S. A. Franchino-Viñas, N. Varacalli, O. Zanusso
We study pair creation for quantum fields of spin , , and in the presence of weak gravitational and gauge backgrounds. Using resummed heat-kernel techniques, we obtain…
Conformally-flat gravitational analogues to the Schwinger effect
S. A. Franchino-Viñas, F. D. Mazzitelli, S. Pla
We study particle creation for scalar fields in conformally flat spacetimes using resummed heat-kernel techniques. We make use of an analogy between quantum scalar fields in confor…
Strong-field regime within effective field theory
Sebastián Franchino-Viñas, Jérémie Quevillon, Diego Saviot
Building upon the Covariant Derivative Expansion, we develop a method to compute effective actions that is able to capture non-perturbative effects induced by strong background fie…
Heat Kernels and Resummations: the Spinor Case
S. A. Franchino-Viñas, C. García-Pérez, F. D. Mazzitelli +2
Among the available perturbative approaches in quantum field theory, heat kernel techniques provide a powerful and geometrically transparent framework for computing effective actio…
Resummed effective actions and heat kernels: the Worldline approach and Yukawa assisted pair creation
Filippo Fecit, Sebastián Franchino-Viñas, Francisco D. Mazzitelli
We adapt the Worldline Formalism to obtain resummed expressions for the effective action and the heat kernel of a quantum scalar field coupled to a Yukawa background. The resummati…
Strong-field resummed heat kernels and effective actions: inhomogeneous fields
S. A. Franchino-Viñas, C. García-Pérez, F. D. Mazzitelli +3
We study the strong-field limit of a theory involving a quantum scalar field coupled to a vector background, which can be either an electromagnetic field or a non-gauge field coupl…
