Quantum chemical multi-reference methods | Hans Lischka


With the publication of over 360 scientific papers that have been cited more than 22,000 times I currently achieve an h-index of 79 according to Google Scholar.

In my work I strive for the best quality and results by connecting and collaborating with fellow scientists globally. Visiting residencies and thereby growing my network have been a constant principle of my career.

My research focuses on defect structures and chemical reactions in materials with current applications to graphene nanoribbons, excitonic coupling and charge transfer in π-conjugated  oligomers as applied to organic photovoltaics and the photostability of DNA.

I am one of the originators and main developers of the software package Columbus for ab initio multireference calculations, and one of the originators and co-developer of the surface-hopping program Newton-X.

The development and implementation of highly-parallelized multi reference configuration interaction (MRCI) with analytical energy gradients and analytical nonadiabatic couplings within Columbus are pioneering in this field.
