Cavity-mediated localization and collective electron correlation phases
Dominik Sidler, Francesco Greco, Michael Ruggenthaler +1
Collective strong coupling of molecular ensembles to optical cavities opens a route to modifying matter through genuinely collective electronic correlations. Yet even in the absenc…
Cavity Control of Strongly Correlated Electrons Beyond Resonant Coupling
Lukas Grunwald, Xinle Cheng, Emil Viñas Boström +4
Interfacing materials with electromagnetic cavities offers a route to modify equilibrium properties through structured vacuum fluctuations. The coupling between light and correlate…
Testing electron-photon exchange-correlation functional performance for many-electron systems under weak and strong light-matter coupling
Iman Ahmadabadi, I-Te Lu, Leonardo A. Cunha +3
We present results of a photon-free exchange-correlation functional within the local density approximation (pxcLDA) for quantum electrodynamics density functional theory (QEDFT) th…
Multimode equilibrium approximations in light-matter systems from weak to strong coupling
Davis M. Welakuh, Vasil Rokaj, Michael Ruggenthaler +1
In this work, we detail different approaches to treat multi-mode photonic environments within non-relativistic quantum electrodynamics in the long-wavelength approximation efficien…
Quantum-Electrodynamical Density-Functional Theory Exemplified by the Quantum Rabi Model
Vebjørn H. Bakkestuen, Vegard Falmår, Maryam Lotfigolian +3
The key features of density-functional theory (DFT) within a minimalistic implementation of quantum electrodynamics are demonstrated, thus allowing to study elementary properties o…
Analytic Model Reveals Local Molecular Polarizability Changes Induced by Collective Strong Coupling in Optical Cavities
Jacob Horak, Dominik Sidler, Thomas Schnappinger +3
Despite recent numerical evidence, one of the fundamental theoretical mysteries of polaritonic chemistry is how and if collective strong coupling can induce local changes of the el…
