PROJECT TITLE :

Ultrafast Charge Dynamics in an Amino Acid Induced by Attosecond Pulses

ABSTRACT:

In the past few years, attosecond techniques are implemented for the investigation of ultrafast dynamics in molecules. The generation of isolated attosecond pulses characterised by a relatively high photon flux has unfolded new potentialities in the study of molecular dynamics. During this paper, we tend to report on experimental and theoretical results of ultrafast charge dynamics in a very biochemically relevant molecule, namely, the amino acid phenylalanine. The data represent the primary experimental demonstration of the generation and observation of a charge migration method in a complicated molecule, where electron dynamics precede nuclear motion. The applying of attosecond technology to the investigation of electron dynamics in biologically relevant molecules represents a multidisciplinary work, which can open new research frontiers: those in which few-femtosecond and even subfemtosecond electron processes confirm the fate of biomolecules. It can conjointly open new views for the event of latest technologies, for example, in molecular electronics, where electron processes on an ultrafast temporal scale are essential to trigger and management the electron current on the scale of the molecule.
