Comment on "Spin Contribution to the Ponderomotive Force in a Plasma"
Pavel A. Andreev
TL;DR
This paper critiques a previous study on the spin contribution to ponderomotive force in plasmas, clarifying the correct modeling approach using quantum mechanics.
Contribution
It presents the correct quantum mechanical model for spin effects in plasma ponderomotive forces, correcting prior two-fluid model assumptions.
Findings
The previous two-fluid model is inconsistent with the Pauli equation.
The correct quantum model aligns with fundamental quantum mechanics.
Clarifies the proper treatment of spin in plasma physics.
Abstract
Several years ago, G. Brodin, A. P. Misra, and M. Marklund considered "Spin Contribution to the Ponderomotive Force in a Plasma" Phys. Rev. Lett. \textbf{105}, 105004 (2010). They applied a two fluid model of electron gas where spin-up and spin-down electrons are considered as two different species. Their approach to this problem appears to be in disagreement with the Pauli equation. The correct model is presented in this comment.
