The dynamics of molecules strongly depends on their environment. Hydrogen bonds are an important interaction mitigating these effects and thus are of universal importance in chemistry and (bio)chemistry. To study these effects in detail, we aim at bridging the gap between single isolated molecules and molecules in solvation. This project is embedded in the collaborative Röntgen-Angstrom-Cluster program UDIET with partners in Hamburg (Germany) and Lund (Sweden). It is also closely attached to the International Helmholtz Graduate School HELIOS.
Your project aims to disentangle the influence of single water molecules attached one-by-one to biologically relevant model chromophores on the photo-induced ultrafast electronic and molecular dynamics. This is based on our experience with the control and imaging of isolated microsolvated systems and our collaboration partners’ experience with attosecond laser technology. The size-selected microsolvated systems will be studied using photoelectron- and ion-coincidence-imaging techniques. Recording and correlating all photo fragments allows for a reconstruction of the complete dynamics even in the molecular frame. The hydrogen bond interactions will be investigated by varying the geometries between the solvent and the biomolecule while investigating the induced photo-driven processes. These studies will be performed in well-defined conditions in ultrahigh vacuum, using molecular beams and light sources such as high-intensity ultrashort-pulse lasers, synchrotrons and x-ray free-electron lasers (FELs).
A university degree in a relevant field.
A university degree in physics, chemical physics, or in a comparable relevant field is required. Preference will be given to candidates with a completed MSc. We expect experience in areas covering quantum mechanics, molecular physics, molecular dynamics, molecular beams, vacuum equipment, ultrafast laser sources including optics and programming. Experience with large-scale facilities such as synchrotrons or free-electron lasers is an advantage. Very good communication skills in English and/or German are required.
Universität Hamburg—University of Excellence is one of the strongest research educational institutions in Germany. Our work in research, teaching, educational and knowledge exchange activities is fostering the next generation of responsible global citizens ready to tackle the global challenges facing us. Our guiding principle “Innovating and Cooperating for a Sustainable Future” drives collaboration with academic and nonacademic partner institutions in the Hamburg Metropolitan Region and around the world. We would like to invite you to be part of our community to work with us in creating sustainable and digital change for a dynamic and pluralist society.The Free and Hanseatic City of Hamburg promotes equal opportunity. As women are currently underrepresented in this job category at Universität Hamburg according to the evaluation conducted under the Hamburg act on gender equality (Hamburgisches Gleichstellungsgesetz, HambGleiG), we encourage women to apply for this position. Equally qualified and suitable female applicants will receive preference.
Severely disabled and disabled applicants with the same status will receive preference over equally qualified non-disabled applicants.
