Using a simple conductance asymmetry metric, researchers disentangled coexisting spin, vibrational, and orbital excitations within a single cobaltocene molecule, potentially enabling new approaches for single-molecule quantum computing. Learn more: go.aps.org/4gZMf0F
A scientific schematic featuring a plot and 3D renderings of ball and stick chemical structures of cobaltocene. On the bottom left is a blue sphere with a black arrow through it that points up and to the right. On the top left is a red sphere with a black arrow through it that points down and to the left. In between them is a cobaltocene molecule. To the right is a blue curve depicting a differential conductance spectrum. Above and below the spectrum are green and red electron density lobes and atomic structures showing the vibrational and orbital excitations at different energy levels.
