Ultrafast real-time vibronic coupling of a breather soliton in trans-polyacetylene using a few cycle pulse

Abstract

The ultrafast electron-phonon coupling dynamics due to a breather soliton inducing amplitude and frequency modulations after photoexcitation in trans-polyacetylene was observed by ultrafast multicolor spectroscopy. The results were in good agreement with recent theoretical predictions. (C) 2009 Optical Society of America
