Effective enhancement of the electron-phonon coupling driven by nonperturbative electronic density fluctuations
Emin Moghadas, Matthias Reitner, Tim Wehling +3
We present a dynamical mean-field study of the nonperturbative electronic mechanisms, which may lead to significant enhancements of the electron-phonon coupling in correlated elect…
Impact of nonlocal spatial correlations for different lattice geometries
Marvin Leusch, Alessandro Toschi, Andreas Hausoel +2
We analyze the impact of the lattice geometry on the thermodynamic transition to magnetically ordered phases in strongly interacting electron systems for various Bravais lattices i…
Fragility of local moments against hybridization with flat bands
Max Fischer, Arianna Poli, Lorenzo Crippa +6
The Kondo screening of a localized magnetic moment crucially depends on the spectral properties of the electronic bath to which it is coupled. Unlike textbook examples, realistic s…
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…
