✓ Portable graph bundle live · download bundle · merged state

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

Both strong local electron correlations and judicious ligand selection to promote orbital hybridization are key prerequisites to realizing altermagnetism in strongly correlated systems.

C2weakest assumption

The state-of-the-art quantum many-body frameworks used accurately capture nonlocal screening, Mott gaps, and hybridization effects without approximations that would alter the reported trends in spin-band splitting.

C3one line summary

Strong correlations suppress spin splitting in MnF2 via band narrowing, enable it in MnTe through Mn 3d-Te 5p hybridization, and produce itinerant splitting without local moments in RuO2.
