Outline of Final Research Achievements

Fast light means phenomena that optical pulses propagate faster than c i.e. light velocity in vacuum, or even negative velocity in anomalous dispersion media. The purpose of the present research is to investigate the information velocity, causality in the fast light systems and elucidate the underlying physics in terms of relativity
