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…
Surface-mediated ultra-strong cavity coupling of two-dimensional itinerant electrons
Christian J. Eckhardt, Andrey Grankin, Dante M. Kennes +5
Engineering phases of matter in cavities requires effective light-matter coupling strengths that are on the same order of magnitude as the bare system energetics, coined the ultra-…
Collectively-modified inter-molecular electron correlations: The connection of polaritonic chemistry and spin glass physics
Dominik Sidler, Michael Ruggenthaler, Angel Rubio
Polaritonic chemistry has garnered increasing attention in recent years due to pioneering experimental results, which show that site- and bond-selective chemistry at room temperatu…
The relevance of degenerate states in chiral polaritonics
Carlos M. Bustamante, Dominik Sidler, Michael Ruggenthaler +1
In this work we explore theoretically whether a parity-violating/chiral light-matter interaction is required to capture all relevant aspects of chiral polaritonics or if a parity-c…
Relativistic Linear Response in Quantum-Electrodynamical Density Functional Theory
Lukas Konecny, Valeriia P. Kosheleva, Heiko Appel +2
We present the theoretical derivation and numerical implementation of the linear response equations for relativistic quantum electrodynamical density functional theory (QEDFT). In…
Cavity engineered phonon-mediated superconductivity in MgB from first principles quantum electrodynamics
I-Te Lu, Dongbin Shin, Mark Kamper Svendsen +5
Strong laser pulses can control superconductivity, inducing non-equilibrium transient pairing by leveraging strong-light matter interaction. Here we demonstrate theoretically that…
