Effective Equilibrium Theory of Quantum Light-Matter Interaction in Cavities: Extended Systems and the Long Wavelength Approximation
Mark Kamper Svendsen, Michael Ruggenthaler, Hannes Hübener +4
When light and matter interact strongly, the resulting hybrid system inherits properties from both constituents, allowing one to modify material behavior by engineering the surroun…
Solution of the v-representability problem on a one-dimensional torus
Sarina M. Sutter, Markus Penz, Michael Ruggenthaler +2
We provide a solution to the v-representability problem for a non-relativistic quantum many-particle system on a ring domain in terms of Sobolev spaces and their duals. Any one-par…
Testing the Renormalization of the von Klitzing Constant by Cavity Vacuum Fields
Josefine Enkner, Lorenzo Graziotto, Felice Appugliese +7
In light of recent developments demonstrating the impact of cavity vacuum fields inducing the breakdown of topological protection in the integer quantum Hall effect, a compelling q…
Exchange-only virial relation from the adiabatic connection
Andre Laestadius, Mihály A. Csirik, Markus Penz +4
The exchange-only virial relation due to Levy and Perdew is revisited. Invoking the adiabatic connection, we introduce the exchange energy in terms of the right-derivative of the u…
Non-perturbative Mass Renormalization Effects in Non-relativistic Quantum Electrodynamics
Davis M. Welakuh, Vasil Rokaj, Michael Ruggenthaler +1
In this work we investigate the effects that multi-mode photonic environments, e.g., optical cavities, have on the properties of quantum matter. We highlight the importance of the…
Cavity-Born-Oppenheimer Hartree-Fock Ansatz: Light-matter Properties of Strongly Coupled Molecular Ensembles
Thomas Schnappinger, Dominik Sidler, Michael Ruggenthaler +2
Experimental studies indicate that optical cavities can affect chemical reactions, through either vibrational or electronic strong coupling and the quantized cavity modes. However,…
