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

Current pulses applied via scanning tunneling microscopy can both write and erase persistent nanometer-scale patterns on the surface of WTe2. These patterns consist of apparent picometer in-plane and out-of-plane atomic displacements, accompanied by changes to the local density of states.

C2weakest assumption

The observed picometer displacements represent true persistent structural changes due to ferroelectric switching and modulation of the Peierls distortion, rather than transient tip-induced effects, imaging artifacts, or non-structural electronic changes.

C3one line summary

STM current pulses create reversible picometer-scale atomic displacements in WTe2, enabling persistent nanoscale ferroelectric switching and Peierls distortion modulation.
