• atomic-scale conductors, due to the ballistic nature of electronic transport, the conductance should not change with the length of the conductor. However, chain-length dependent oscillations in the conductance in monoatomic chains have been reported by the name of parity oscillations or even–odd

• the current-induced parts of this matrix in metallic systems are long-ranged, especially at low bias. This nonlocality is essential for the characterisation of nonconservative atomic dynamics under current beyond the nanoscale. Keywords: atomic-scale conductors; current-induced forces; electronic
