Approach to Chandrasekhar-Kendall-Woltjer State in a Chiral Plasma

Understand

We study the time evolution of the magnetic field in a plasma with a chiral magnetic current.

• The Vector Spherical Harmonic functions (VSH) are used to expand all fields.
• We define a measure for the Chandrasekhar-Kendall-Woltjer (CKW) state, which has a simple form in VSH expansion.
• We propose the conditions for a general class of initial momentum spectra that will evolve into the CKW state.
