Welcome to the ICD resarch unit page!
The topic of this research unit is the investigation of a novel, recently discovered mechanism for the transformation of electronic energy created by excitation or ionization with radiation in the UV and far beyond, or with energetic particles. In addition to photoemission from an excited atom and the emission of an Auger-electron, Intermolecular or Interatomic Coulombic Decay provides a third, additional decay mechanism, which is alternative to fluorescence for low excitation energies, and to emission of an Auger electron for more highly excited states. ICD is not a resonant process, and is therefore expected to occur under general conditions. Thus it is expected to find ICD in many systems and configurations.
Putting ICD in a broader context, it bridges the gap between fundamental research on the correlated motion of electrons and nuclei and more applied research, for example, on the influence of low kinetic energy electrons in radiation chemistry. In this research unit we expect to contribute not only exciting experiments on the ultrafast dynamics of the electronic cloud but also new ideas directed towards new fields of application.
This research unit is a collaboration of the leading scientists in ICD in Germany and Austria from Goethe-Universität Frankfurt, Universität Innsbruck, Universität Heidelberg, Universität Hamburg, Max-Planck-Institut für Plasmaphysik and Helmholtz Zentrum Berlin [More].

Intermolecular Coulombic Decay in Biology: The Initial Electron Detachment from FADH- in DNA Photolyases
J. Phys. Chem. Lett., 4, 943 (2013)
Intermolecular coulombic decay (ICD) is an efficient mechanism of low-energy electron generation in condensed phases and is discussed as their potential source in living cells, tissues, and materials. The first example of ICD as an operating mechanism in real biological systems, that is, in the DNA repair enzymes photolyases, is presented. Photolyase function involves light-induced electron detachment from a reduced flavin adenine dinucleotide (FADH–), followed by its transfer to the DNA-lesion triggering repair of covalently bound nucleobase dimers. Modern quantum chemical methods are employed to demonstrate that the transferred electron is efficiently generated via a resonant ICD process between the antenna pigment and the FADH– cofactors.
22.11.2012 - ICD Symposium during the DPG Spring Meeting
We would like to invite you to a symposium on ICD and related processes. The symposium will take place during the DPG Spring meeting of the AMOP section in march 2013. Besides talks of invited international speakers, several talks from national speakers will be given.
Vitali Averbukh (Imperial College London)
Till Jahnke (University of Frankfurt)
Gunnar Öhrwall (MAX-Lab)
Kirsten Schnorr (MPI für Kernphysik)
In addition we would like to point out that this contributed session is also part of the ICD Symposion.

03.09.2012 - Announcement of the "Kick-Off" Meeting
The Kick-Off Meeting is scheduled for January 2012 and will take place at the Sparkassenakademie Schloss Waldthausen in Budenheim. As an important organizational part of this research unit all individual groups will be present. In addition some international speakers have been invited. Confirmed externally speakers are Kiyoshi Ueda (Tohoku University), Robert Moshammer (MPI f. Kernphysik), Andre Knie (Uni Kassel), Arno Ehresmann (Uni Kassel), Mathieu Gisselbrecht (Lund University), Carsten Müller (Uni Düsseldorf) and Petr Slavicek (Technical University Prague).
Further information and the registration can be found here. If have any questions about the "kick-off" meeting please contact Prof. Reinhard Dörner.
03.09.2012 - Launch of the ICD Research Unit Webpage
I am glad to announce that the Webpage of this research unit is now finally launched. While it is still incomplete and under constant development the main features for members of the research unit are working. To support the organization and communication it is possible to use an intern dashboard-structured section and register for upcoming meetings. The data exchange is also temporarily possible within the intern section but will be eventually exchanged with a different system.
During the next weeks more content will be added to webpage and made accessible for public users. In addition a system for video conferencing is planned.
If you have any questions or suggestions please write an email to the webmaster
