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…

Resummed heat kernel and effective action for Yukawa and QED
S. A. Franchino-Viñas, C. García-Pérez, F. D. Mazzitelli +2
In this letter, we prove the existence of resummed expressions for the diagonal of the heat kernel and the effective action of a quantum field which interacts with a scalar or an e…
