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 …

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 …

Last Thursday the PhDs of my graduate school gathered again for our self-organised mini conference, named Annual Colloquium. Having organised this event myself as well a couple of years back, I had rather mixed feelings this time, since I most likely not be around in Heidelberg for another AC.

For …

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 …

Yesterday I gave a talk at our annual group retreat at the Darmstädter Haus in Hirschegg, Kleinwalsertal. For this talk I expanded the slides from my lazy matrix talk in Kiel, incorporating a few of the more recent Coulomb-Sturmian results I obtained.

Most importantly I added a few slides to …

On my way back from Copenhagen last Thursday I stopped in Kiel to visit Henrik Larsson and some other people from last year's Deutsche Schülerakademie in Grovesmühle.

Henrik is doing his PhD at the group of Prof. Bernd Hartke and so I took the opportunity and gave a short talk …

# look4bas: Small script to search for Gaussian basis sets

In the past couple of days I hacked together a small Python script, which searches through the EMSL basis set exchange library of Gaussian basis sets via the commandline.

Unlike the webinterface it allows to use

# A short return to Cambridge

About two weeks ago, on Friday the 13th of March, I was invited back to the Chemistry Department at the University of Cambridge. As part of their Theoretical Chemistry Informal Seminar talk series I was asked to give a short talk (Abstract) about my current research. Needless to say that …

Last Monday and Tuesday this year's most important event of the HGS Mathcomp (my graduate school) took place — the Annual Colloquium. Being part of the organising committee we stepped into the footsteps of the previous ACs and planned it as a short two-day conference with graduate students presenting their project …

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 …
