RESEARCH AREA


Brief Introduction

 

»Amongst the many words used to express contemporary scientific challenges, we list some key words relevant to our research. From a chemists perspective, all of these could be   expressed by the terms "single molecule", "light", and "time". For example, the constant trend in miniaturization of electronics now aims to develop devices based on single molecules. Likewise, unraveling the complicated phenomena in biosystems cannot be accomplished without understanding chemical processes on the molecular scale. In addition, many intriguing chemical phenomena such as photosynthesis, or more broadly photochemistry, entail the interaction of molecules with light. Ultimately all the chemical processes mentioned above can be described by the dynamics of electrons and nuclei in molecular systems. It is essential therefore to study such ultrafast dynamics in a time-resolved manner. Our research aims to develop theoretical methods to capture these fleeting molecular states, which will then be used to explain unresolved experimental observations and, ultimately, to design novel devices. We will be particularly focused on electron transfer phenomena over length scales covering simple molecules all the way up to complex bio-molecules, and with time scales ranging from atto- to pico-seconds.
