Understanding polaritonic chemistry from ab initio quantum electrodynamics
Michael Ruggenthaler, Dominik Sidler, Angel Rubio
In this review we present the theoretical foundations and first principles frameworks to describe quantum matter within quantum electrodynamics (QED) in the low-energy regime. Havi…
The structure of the density-potential mapping. Part I: Standard density-functional theory
Markus Penz, Erik I. Tellgren, Mihály A. Csirik +2
The Hohenberg-Kohn theorem of density-functional theory (DFT) is broadly considered the conceptual basis for a full characterization of an electronic system in its ground state by…
Exact Solution for A Real Polaritonic System Under Vibrational Strong Coupling in Thermodynamic Equilibrium: Absence of Zero Temperature and Loss of Light-Matter Entanglement
Dominik Sidler, Michael Ruggenthaler, Angel Rubio
The first exact quantum simulation of a real molecular system (HD) under strong ro-vibrational coupling to a quantized optical cavity mode in thermal equilibrium is presented.…
Exchange energies with forces in density-functional theory
Nicolas Tancogne-Dejean, Markus Penz, Andre Laestadius +3
We propose exchanging the energy functionals in ground-state DFT with physically equivalent exact force expressions as a new promising route towards approximations to the exchange-…
Frequency-dependent Sternheimer linear-response formalism for strongly coupled light-matter systems
Davis M. Welakuh, Johannes Flick, Michael Ruggenthaler +2
The rapid progress in quantum-optical experiments especially in the field of cavity quantum electrodynamics and nanoplasmonics, allows to substantially modify and control chemical…
New Class of Landau Levels and Hall Phases in a 2D Electron Gas Subject to an Inhomogeneous Magnetic Field: An Analytic Solution
Dominik Sidler, Vasil Rokaj, Michael Ruggenthaler +1
An analytic closed form solution is derived for the bound states of electrons subject to a static, inhomogeneous (-decaying) magnetic field, including the Zeeman interaction.…
