Today’s Spotlight image features a scanning tunneling microscope image, by Michael Crommie, showing an artificial atomic nucleus on graphene, consisting of five pairs of calcium atoms (slightly darker circles at center), in an electron cloud that is on the verge of collapse.
Atomic collapse, a phenomenon first predicted in the 1930s based on quantum mechanics and relativistic physics but never before observed, has now been seen for the first time in an “artificial nucleus” simulated on a sheet of graphene. The observation not only provides confirmation of long‑held theoretical predictions, but could also pave the way for new kinds of graphene‑based electronic devices, and for further research on basic physics.
