Ab initio Light-Matter Group

TU Wien, Institute for applied physics

Our interest lies at the interface of established research areas – the uncharted territory in between the beaten paths.

We interweave 3 domains to a unique approach at the forefront of applied computational materials science:

(i) development of theoretical tools to describe the self-consistent and non-perturbative interaction between (quantized) electromagnetic fields and realistic matter from first principles

(ii) advancing green chemistry via polaritonic chemistry, plasmonic catalysis, and chiral polaritonics

(iii) predicting novel quantum-impurity systems, exploring quantum scrambling, and developing near-term quantum algorithmic

New paper out! Dating can be tough, even between impurity molecules and organic crystals. Here, we play the role of a matchmaker and identify new couples that could build a bright future as quantum light-matter interface (Öhman et al., 2026)
