3D Images of a Gold Nanocrystal 10, 60 and 110 Picoseconds after Excitation with a Laser

Caption

The acoustic phonons can be visualized on the surface as regions of contraction (blue) and expansion (red). Also shown are two-dimensional images comparing the experimental results with theory and molecular dynamics simulation. The scale bar is 100 nanometers.
