Accurate Modeling of Rydberg Atoms and Their Interactions: Theory and Implementation in PairInteraction
Johannes Mögerle, Frederic Hummel, Alicia Keil +8
Rydberg atoms provide a powerful platform for exploring strongly interacting quantum systems, both in free space and in structured electromagnetic environments, with growing applic…
Coherent cellular dynamical mean-field theory: a real-space quantum embedding approach to disorder in strongly correlated electron systems
Patrick Tscheppe, Marcel Klett, Henri Menke +4
We formulate a quantum embedding algorithm in real-space for the simultaneous theoretical treatment of nonlocal electronic correlations and disorder, the coherent cellular dynamica…
Single-particle spectra and magnetic susceptibility in the Emery model: a dynamical mean-field perspective
Yi-Ting Tseng, Mário O. Malcolms, Henri Menke +3
We investigate dynamical mean-field calculations of the three-band Emery model at the one- and two-particle level for material-realistic parameters of high- superconductors. O…
Rise and Fall of the Pseudogap in the Emery model: Insights for Cuprates
M. O. Malcolms, Henri Menke, Yi-Ting Tseng +4
The pseudogap in high-temperature superconducting cuprates is an exotic state of matter, displaying emerging Fermi arcs and a momentum-selective suppression of states upon cooling.…
Engineering correlated Dirac fermions and flat bands on SiC with transition-metal adatom lattices
Henri Menke, Niklas Enderlein, Yi-Ting Tseng +5
We propose three transition-metal adatom systems on SiC surfaces as a versatile platform to realize massless Dirac fermions and flat bands with strong electronic correlations. Usin…
