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

Fluctuational electrodynamics simulations reveal that these resonances lie within the SiC Reststrahlen band, redshift for thinner nanowires, and yield a four-fold enhancement of thermal conductance. This maximum enhancement occurs when the separation gap nearly matches the nanowire thickness.

C2weakest assumption

The assumption that the observed enhancement is genuinely dominated by multiple distinct corner and edge modes rather than other effects, and that the simulations accurately capture the physics without needing experimental validation.

C3one line summary

Square SiC nanowires achieve four-fold higher near-field thermal conductance via multiple corner and edge phonon-polariton resonances when the gap nearly matches nanowire thickness.
