Title: Pressure Tensor Elements Breaking the Frozen-In Law During Reconnection in Earth’s Magnetotail

Abstract

Aided by fully kinetic simulations, spacecraft observations of magnetic reconnection in Earth’s magnetotail are analyzed. The structure of the electron diffusion region is in quantitative agreement with the numerical model. Of particular interest, the spacecraft data reveal how reconnection is mediated by off-diagonal stress in the electron pressure tensor breaking the frozen-in law of the electron fluid.
