Job announcements relevant to people interested in electronic structure calculations…
Due to the large number of posts recently, there is currently a delay of several weeks between posts being submitted and the corresponding emails being distributed to all users. Please bear with us while we try to improve this. In the meantime – and until this notice is removed – it would assist us considerably if you could submit only important and/or urgent posts and thus help to reduce the size of the mail queue. Under no circumstances should you resend posts multiple times when you find the emails are not distributed immediately.
In light of the Russian military offensive in Ukraine, we request that announcements relating to events, jobs and other activities associated with institutions supported by the Russian and Belarusian states are not posted to the Psi-k forum.
Postdoctoral Positions: Quantum Field Theory Mee ... (No replies)
Back to Job listings...
Two postdoctoral positions are available in the Chair for Theoretical Chemical Physics (TCP), led by Prof. Alexandre Tkatchenko in the Department of Physics and Materials Science (DPhyMS) at the University of Luxembourg (http://www.tcpunilu.com). These positions are embedded within the European Research Council Consolidator Grant "Beyond Static Molecules: Modeling Quantum Fluctuations in Complex Molecular Environments".
We are looking for motivated, independent, and skilled scientists to join our group. As part of the TCP group, researchers will have ample opportunity to exchange ideas, transfer knowledge, and to pick up new expertise. Our publications (https://scholar.google.pl/citations?user=o2t1Pv8AAAAJ&hl=en) provide perspective on our research directions. We have two positions focused on bridging quantum field theory (QFT) and atomistic modeling:
(i) "QFT Perspective on Intermolecular Interactions"
The quantum-mechanical theory of intermolecular interactions is well established [see e.g. https://www.amazon.com/Theory-Intermolecular-Forces-Anthony-Stone/dp/0198789157; Science 351, 1171 (2016)]. However, much less is known about the QED and QFT effects on intermolecular interactions. This project aims to develop a practically-applicable QED/QFT approach based on quantum Drude oscillators for atomic response [arXiv:2101.08701]. Once accomplished, various QED/QFT effects will be studied with the aim to systematically understand their importance in the context of intermolecular interactions.
(ii) "Beyond Perturbative QFT for Atomic Polarization"
The vacuum state in QED/QFT is typically expressed as plane waves and the effect of atoms/molecules on the vacuum state is studied perturbatively or as a boundary condition. This project aims to develop non-perturbative techniques for the interaction between the QED/QFT vacuum and atomic/molecular systems. Examples of applications include first-principles derivation of unusual scaling laws for the electronic polarizability [PRL 121, 183401 (2018); arXiv:2007.02992] or Lamb shift for molecules [see e.g. https://www.nature.com/articles/s41467-020-20473-w%5D.
DPhyMS at Uni.lu is a quickly growing physics department composed of 18 dynamic research groups, spanning the broad domain of condensed matter, molecular, and quantum physics. The University of Luxembourg is a young, dynamic, and well-funded university rapidly growing in international rankings. Luxembourg is a small European country with a very high quality of living and is bordered by France, Belgium, and Germany.
The positions are open to strong applicants with backgrounds in physics, mathematics and/or multidisciplinary background. We offer competitive salary and attractive working environment in one of the most enjoyable European cities (http://www.euraxess.lu).
For more information and applications contact: Prof. Dr. Alexandre Tkatchenko ([email protected]).
