The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We further show, using electron--positron particle-in-cell simulations, that the SG force sorts particles by magnetic-moment projection into opposite sides of a Harris current sheet without measurably changing the global reconnection rate in the tested regime.

C2weakest assumption

The assumption that the fully projected branch parameter Ξ₀ = <Z>/r_L and its effective version Ξ_Eff = P_eff Ξ₀ correctly capture the accumulated SG cross-sheet displacement relative to the relativistic Larmor radius during a diffusion-region transit (as defined in the introduction of the control parameter).

C3one line summary

Introduces the parameter Ξ_Eff to quantify Stern-Gerlach spin sorting in reconnection and reports PIC simulations showing particle sorting by magnetic moment without altering the global reconnection rate.
