Quantum simulation of interlayer charge ordering in Kagome frustrated-magnet

Kumar Ghosh, Sabre Kais

Interlayer exchange drives a sharp ferroelectric-to-antiferroelectric Ice-II transition in bilayer Kagome spin ice at J_perp/J1 approximately 0.042.

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

Interlayer exchange drives a sharp ferroelectric-to-antiferroelectric Ice-II transition at (J⊥/J1)*≈0.042, stable across five decades of annealing time and forbidden in any single-layer system.

C2weakest assumption

The D-Wave Advantage2 embedding and annealing schedule faithfully reproduce the target bilayer Kagome Hamiltonian without dominant hardware noise or embedding errors that would shift the reported transition point.

C3one line summary

Bilayer Kagome spin ice on quantum annealer exhibits sharp Ice-II transition at J_perp/J1 ≈ 0.042 with independent control of monopoles via quantum drive and charge order via interlayer coupling.
