Vortex driven Schwingrer pair creation in the magnetosphere of SgrA*

TL;DR

This paper investigates how vortex-driven magnetic fields in the SgrA* magnetosphere can trigger efficient Schwinger pair creation through magneto-centrifugal effects, leading to significant electron-positron production.

Contribution

It introduces a novel mechanism where vortex-driven magnetic fields enhance Schwinger pair creation in SgrA*'s magnetosphere, surpassing previous estimates.

Findings

Vortex-driven magnetic fields are significantly stronger than previously thought.

Magneto-centrifugal acceleration leads to charge separation and Langmuir wave excitation.

Electric fields reach Schwinger threshold, causing prolific pair production.

Abstract

In this work, we explore the possibility of Schwinger pair creation triggered by magneto-centrifugal effects in the magnetosphere of SgrA*. We show that these effects become extremely efficient in the presence of a vortex-driven magnetic field, whose strength exceeds previous estimates by several orders of magnitude. The dynamics of magneto-centrifugally accelerated charged particles leads to charge separation, thereby parametrically exciting Langmuir waves. The associated electric field grows exponentially and upon reaching the Schwinger critical threshold, initiates efficient electron-positron pair production, which is ultimately saturated by annihilation processes.
