The Ferroelectric Photo-Groundstate of SrTiO: Cavity Materials Engineering
Simone Latini, Dongbin Shin, Shunsuke A. Sato +4
Optical cavities confine light on a small region in space which can result in a strong coupling of light with materials inside the cavity. This gives rise to new states where quant…
The quantum paraelectric phase of SrTiO from first principles
Dongbin Shin, Simone Latini, Christian Schäfer +4
We demonstrate how the quantum paraelectric ground state of SrTiO can be accessed via a microscopic approach based on density functional theory. At low temperature…
Intermolecular interactions in optical cavities: an ab initio QED study
Tor S. Haugland, Christian Schäfer, Enrico Ronca +2
Intermolecular bonds are weak compared to covalent bonds, but they are strong enough to influence the properties of large molecular systems. In this work, we investigate how strong…
Polaritonic Chemistry: Collective Strong Coupling Implies Strong Local Modification of Chemical Properties
Dominik Sidler, Christian Schäfer, Michael Ruggenthaler +1
Polaritonic chemistry has become a rapidly developing field within the last few years. A multitude of experimental observations suggest that chemical properties can be fundamentall…
Octopus, a computational framework for exploring light-driven phenomena and quantum dynamics in extended and finite systems
Nicolas Tancogne-Dejean, Micael J. T. Oliveira, Xavier Andrade +31
Over the last years extraordinary advances in experimental and theoretical tools have allowed us to monitor and control matter at short time and atomic scales with a high-degree of…
Benchmarking Semiclassical and Perturbative Methods for Real-time Simulations of Cavity-Bound Emission and Interference
Norah M. Hoffmann, Christian Schäfer, Niko Säkkinen +3
We benchmark a selection of semiclassical and perturbative dynamics techniques by investigating the correlated evolution of a cavity-bound atomic system to assess their applicabili…
Relevance of the quadratic diamagnetic and self-polarization terms in cavity quantum electrodynamics
Christian Schäfer, Michael Ruggenthaler, Vasil Rokaj +1
Experiments at the interface of quantum-optics and chemistry have revealed that strong coupling between light and matter can substantially modify chemical and physical properties o…
Dressed-Orbital Approach to Cavity Quantum Electrodynamics and Beyond
S. E. B. Nielsen, C. Schäfer, M. Ruggenthaler +1
We present a novel representation of coupled matter-photon systems that allows the application of many-body methods developed for purely fermionic systems. We do so by rewriting th…
