Conformally-flat gravitational analogues to the Schwinger effect
S. A. Franchino-Viñas, S. A. Franchino-Viñas, F. D. Mazzitelli +1
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…
Entanglement in the Schwinger effect
Dimitrios Kranas, Amaury Marchon, Silvia Pla
We analyze entanglement generated by the Schwinger effect using a mode-by-mode formalism for scalar and spinor QED in constant backgrounds. Starting from thermal initial states, we…
Strong-field resummed heat kernels and effective actions: inhomogeneous fields
S. A. Franchino-Viñas, C. GarcÃa-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…
Heat Kernels and Resummations: the Spinor Case
S. A. Franchino-Viñas, C. GarcÃa-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…
