Quantum electrodynamics of equilibrium systems: A rigorous Maxwell-regularized functional-theoretic formulation
Markus Penz, Christian Jöns, Michael Ruggenthaler +1
A framework for quantum electrodynamics of equilibrium systems is proposed that takes the Maxwell equations as foundational and links them to the structure of density-functional th…
Robustness of quantized Hall resistivity under cavity coupling at zero temperature
Juan Román-Roche, Jie Wang, Michael Ruggenthaler +2
Recent experiments have shown that strong light-matter coupling in electromagnetic cavities can modify transport properties of quantum Hall systems through the formation of Landau…
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…
Linear and nonlinear vibrational excitation driven by molecular polaritons
Wenxiang Ying, Carlos M. Bustamante, Franco P. Bonafé +5
Following our recent numerical study [arXiv:2601.16299 (2026)], we investigate vibrational excitation induced by transient optical driving in molecular ensembles strongly coupled t…
Fluctuation engineering in cavity quantum materials
Hope M Bretscher, Lorenzo Graziotto, Marios H Michael +14
Coupling tailored electromagnetic fluctuations to materials provides a resource for controlling correlated quantum matter. By structuring the frequency, spatial, and modal distribu…
Unified ab initio quantum-electrodynamical density-functional theory for cavity-modified electron-phonon-photon coupling in solids
Benshu Fan, I-Te Lu, Michael Ruggenthaler +1
Quantum-electrodynamical density-functional theory (QEDFT) provides a first-principles framework for describing materials coupled to quantized electromagnetic fields. While QEDFT h…
