1. Interdisciplinary software for electronic structure theory: adcc and DFTK

    Last week, from Wednesday to Friday, I paid the Technical University of Munich (TUM) a short visit for two great opportunities to present my work: Once in the theoretical chemistry group of Professor Wolfgang Domcke and once at the annual meeting of the modeling, analysis and simulation of molecular systems …

  2. Interdisciplinary software development in electronic structure theory (MQM Poster)

    At the beginning of the month, from 30th June till 5th July, I attended the 9th Molecular Quantum Mechanics Conference in my old home Heidelberg. This occasion was a great opportunity to catch up with friends and colleges both in science and from my old circle in Heidelberg as well …

  3. Coulomb Sturmian basis functions in electronic structure theory

    After my first Coulomb Sturmian-related talk at the LCT last November, I was approached by Julien Toulouse and asked whether I could give another talk providing a little more insight into Coulomb Sturmians and their potential.

    A few weeks ago, on 29th March, it was thus about time for a …

  4. PostDoc position at CERMICS / Sorbonne Université

    Last week I started my new position as a postdoctoral fellow at the MATHERIALS team of the Centre d'Enseignement et de Recherche en Mathématiques et Calcul Scientifique (CERMICS) laboratory and Inria Paris with an additional affiliation to the Institut des Sciences du Calcul et des Données at Sorbonne Université. As …

  5. SelfConsistentField.jl: A julia toolbox for coding self-consistent field algorithms

    Over the past half a year I became interested in the julia programming language. It is a rather recent language (version 1.0.0 just released last August), which promises to provide a modern approach to scientific computing. From my experience so far, I like julia a lot. All aspects …

  6. Design of the molsturm quantum-chemistry framework

    A few weeks ago, on 23rd November, I was invited to speak at the mathematics and chemistry seminar (GdT mathématiques et chimie) at Sorbonne Université in Paris. This seminar is a joint meeting of theoretical chemists and mathematicians from the LJLL (Laboratoire Jacques-Louis Lions) and the LCT (Laboratoire de Chimie …

  7. Simulating chemistry: Enabling novel approaches for modelling the electronic structure of molecules

    Last week Wednesday I was invited to present my research in front of a bunch of young researchers from the Heidelberg Laureate Forum visiting our institute. Whilst I would have loved to attend the full week of the forum, I am happy that in this way I was able to …

  8. Franco-German Workshop 2018: Open problems related to the algebraic-diagrammatic construction scheme

    In some of my recent projects, e.g. the PE-ADC paper, I got a little more into method development surrounding the algebraic-diagrammatic construction scheme (ADC). Even though quite a few people from the Dreuw group in Heidelberg are involved with ADC development and we have regular talks on ADC, I …

  9. MES 2018 in Metz: molsturm Towards quantum-chemical method development for arbitrary basis functions

    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 …

  10. Coulomb Sturmians in electronic structure theory (Poster at 16th ICQC)

    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 …

  11. 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 …

  14. Coulomb-Sturmians and molsturm

    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 …

  15. 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 …
