Relay transport of relativistic flows in extreme magnetic fields of stars

POSTER

Abstract

We find that transport of relativistic flows in extreme magnetic fields can be achieved in a relay manner by considering the quantum electromagnetic (QED) cascade process, where photons play a key role as a medium. During the transport, the flow emits particle energy into photons via quantum synchrotron radiation and then gain particles back by magnetic pair creation, forming a ``particle-photon-particle" relay. Particle-in-cell simulations demonstrate that forward transport of the flow density is realized by a self-replenishment process with photon-pair cascades, while that of the flow energy is accomplished due to a new coupling path through radiation of photons. This novel transport mechanism is closely associated with jet generation and disk accretion around the neutron star of X-Ray Binaries, offering a potential explanation for the powerful jets observed there.
