Magnetic reconnection under extreme conditions

Determine how magnetic reconnection operates under extreme conditions involving intense radiation, relativistic environments, and quantum-electrodynamic effects relevant to astrophysical systems.

Background

The paper identifies extreme-condition reconnection as a major unresolved problem outside the direct parameter range of the FLARE facility. The question concerns how radiation, relativistic effects, and quantum electrodynamics modify reconnection in extreme astrophysical environments.

In particular, precursor emission associated with binary neutron star mergers and driven by plasmoid coalescence has been discussed in previous studies; however, its validity in relativistic regimes with strong radiative and pair-production effects remains unclear.
