1. Towards quantum-chemical method development for arbitrary basis functions

    Last week we submitted the molsturm design paper titled Towards quantum-chemical method development for arbitrary basis functions. This manuscript is a condensed summary of the arguments about design and implementation of a basis-function independent self-consistent field scheme (SCF) already presented in my PhD thesis.

    Our approach to a basis-function-independent electronic …

  2. Aachen: Beyond Gaussian-type orbitals

    From Monday till Wednesday this week I was invited to the computational mathematics research group of Prof. Dr. Benjamin Stamm at the RWTH Aachen University. In retrospect I am very thankful for the invitation, since the three days turned out to be filled with fruitful discussions, scientific exchange and brainstorming …

  3. Oberwolfach reports: Molsturm modular electronic structure theory framework

    As announced in my previous post about the Oberwolfach workshop on Mathematical Methods in Quantum Chemistry, the proceedings of each Oberwolfach workshop are published in the form of an article in the Oberwolfach reports. For this purpose each speaker is asked for an extended abstract summarising the content of his …

  4. Oberwolfach workshop: Mathematical Methods in Quantum Chemistry

    Last week I was invited to the Mathematical Research Institute Oberwolfach (Mathematisches Forschungsinstitut Oberwolfach) for a workshop about Mathematical Methods in Quantum Chemistry. I am really grateful to the organisers Eric Cancès, Gero Friesecke, Trygve Helgaker and Lin Lin for asking me to join this meeting as it turned out …

  5. Lazy matrices talk from the IWR school 2017

    As mentioned in a previous post on this matter last month, from 2nd to 6th October, the IWR hosted the school Mathematical Methods for Quantum Chemistry, which I co-organised together with my supervisors Andreas Dreuw and Guido Kanschat as well as the head of my graduate school Michael Winckler.

    From …

  7. A thankful goodbye

    As announced on our group website, Dr. Michael Wormit, passed away in a tragic accident a week ago Saturday, the 14th of March. Michael's loss leaves a gap behind that cannot be closed — both on a scientific and on a personal level.

    I myself am thankful and proud that I …

  8. PhD Project: Finite Element Methods in Quantum Chemistry

    In January I officially started my PhD in the Theoretical Chemistry group of Prof. Dr. Andreas Dreuw at the Interdisziplinäres Zentrum für wissenschaftliches Rechnen of the Ruprecht-Karls-Universität Heidelberg. The principle aim of the project is to replace the common formalism of using atom-centered basis functions (e.g. Gaussian atomic orbitals …

  9. SSH through SSH SOCKS Proxy

    Setting up a SOCKS Proxy using ssh

    Port forwarding in ssh is really great. Next to local and remote forwarding there is also dynamic port forwarding that essentially turns the ssh server into a SOCKS Proxy server. This means that you can actually route all the traffic of a local …
