A Shortcut to Self-Consistent Light-Matter Interaction and Realistic Spectra from First-Principles
Christian Schäfer, Göran Johansson
We introduce a simple approach how an electromagnetic environment can be efficiently embedded into state-of-the-art electronic structure methods, taking the form of radiation-react…
A perspective on ab initio modeling of polaritonic chemistry: The role of non-equilibrium effects and quantum collectivity
Dominik Sidler, Michael Ruggenthaler, Christian Schäfer +2
This perspective provides a brief introduction into the theoretical complexity of polaritonic chemistry, which emerges from the hybrid nature of strongly coupled light-matter state…
Making ab initio QED functional(s): Non-perturbative and photon-free effective frameworks for strong light-matter coupling
Christian Schäfer, Florian Buchholz, Markus Penz +2
Strong light-matter coupling provides a promising path for the control of quantum matter where the latter is routinely described from first-principles. However, combining the quant…
Simulating terahertz field-induced ferroelectricity in quantum paraelectric SrTiO
Dongbin Shin, Simone Latini, Christian Schafer +5
Recent experiments have demonstrated that light can induce a transition from the quantum paraelectric to the ferroelectric phase of SrTiO. Here, we investigate this terahertz f…
Shining Light on the Microscopic Resonant Mechanism Responsible for Cavity-Mediated Chemical Reactivity
Christian Schäfer, Johannes Flick, Enrico Ronca +2
Strong light-matter interaction in cavity environments is emerging as a promising approach to control chemical reactions in a non-intrusive and efficient manner. The underlying mec…
