Abstract
We demonstrate that the dynamically assisted Schwinger mechanism, which typically requires the superposition of two distinct electromagnetic fields, can be effectively realized using a single Sauter-type electric field with a vibrating position. We compare it with a conventional oscillating field of the same strength and frequency, showing that the vibrating field is more efficient. Its stable electric force suppresses both virtual particle annihilations and Pauli blocking. Furthermore, we verify that the underlying mechanism in the vibrating field is analogous to that of a combined field. Our study proposes a new approach for testing the Schwinger process without requiring the precise alignment of multiple beams.
