Operator lifetime and the force-free electrodynamic limit of magnetised holographic plasma

Poovuttikul, Napat and Rajagopal, Aruna (2021) 'Operator lifetime and the force-free electrodynamic limit of magnetised holographic plasma.', Journal of High Energy Physics, 2021 (9).


Using the framework of higher-form global symmetries, we examine the regime of validity of force-free electrodynamics by evaluating the lifetime of the electric field operator, which is non-conserved due to screening effects. We focus on a holographic model which has the same global symmetry as that of low energy plasma and obtain the lifetime of (non-conserved) electric flux in a strong magnetic field regime. The lifetime is inversely correlated to the magnetic field strength and thus suppressed in the strong field regime.
