This weekend I attended the MRMCD18 in Darmstadt, which is one of the many chaos events where a few hundred people interested in computer science, hacking, making, politics and society gather for a weekend of talks, coding and discussion. Having participated in this event regularly in the past few years …read more
Currently I am attending the Molecular Electronic Structure 2018 conference in Metz, an electronic-structure theory conference intended for researchers working on novel methodologies, such as explicit correlation, density matrix theory, stochastic approaches or on discretisation techniques going beyond Gaussian-type orbitals.
Especially the latter aspect fits well to the kind of …read more
Yesterday the journal of chemical theory and computation accepted our manuscript titled Polarizable Embedding Combined with the Algebraic Diagrammatic Construction: Tackling Excited States in Biomolecular Systems. In this work we describe the combination of the polarisable embedding (PE) scheme for including environmental effects with the algebraic-diagrammatic construction (ADC) approach.
The …read more
Last week from 18th till 23rd June I attended the 16th International Congress of Quantum Chemistry (ICQC) in Menton, France. Apart from the absolutely stunning scenery at the French Riviera as well as the historic conference building, the conference was a great opportunity to meet up and discuss with people …read more
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 …read more
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 …read more
Finally, after quite some years of work I have successfully defended my PhD thesis with the title Development of a modular quantum-chemistry framework for the investigation of novel basis functions on 22nd May. An electronic version of the text has now been published online.
To make the topic of my …read more
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 …read more
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 …read more
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 …read more
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 …read more
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 …read more
Thursday a week ago I gave a brief introductory talk in our Heidelberg Chaostreff about the Bohrium project. Especially after the HPC day at the Niels Bohr Institute during my recent visit to Copenhagen, I became rather enthusiastic about Bohrium and wanted to pass on some of my experiences.
The …read more
From 2nd to 6th October 2017 the IWR hosts the school Mathematical Methods for Quantum Chemistry, which aims at shining some light into the simulation of quantum chemical problems and their mathematical properties. I am very happy to be part of the organising committee for this school, especially since I …read more
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 useread more

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 …read more
Last Thursday I gave a talk (in German) in our local Chaostreff in Heidelberg — the NoName e.V. The main topic was to introduce the various cryptographic algorithms used in modern cryptography and to give practical advice how to improve the default configuration even further. The talk mainly focuses on …read more
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 …read more
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 …read more
Especially for server's which are required to run 24/7 it is absolutely crucial that one stays updated on the machine's status. E.g. using programs like theread more

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 …read more
Last week I updated the OS on my SSD-only laptop to Debian Jessie and I thought that would be a good opportunity to finally set up full-disk encryption(FDE) on that machine as well. Against my usual policy I did not do so initially fearing the possible performance drawbacks from …read more
