Time Dependent Electron Density (VIDEO) Forschungsverbund Berlin This video is under embargo. Please login to access this video. Caption Left: Time dependent electron density on the sulfate ion shown in Fig. 1 between delay times of 2.7 ps and 5.1 ps. The change of charge density is shown with an amplitude 100 times larger than the experimental value. Right: Time-dependent current density flowing along the crystal's a axis, as derived from the transient electron density. The current density oscillates with a 90 degrees phase shift relative to the electron density. Credit MBI Berlin Usage Restrictions The video may only be used with appropriate caption and credit.
