Magnetic instabilities in three- and higher-dimensional Hubbard models with different lattice geometries: Impact of nonlocal spatial correlations
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 +5
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…
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…
Engineering correlated Dirac fermions and flat bands on SiC with transition-metal adatom lattices
Henri Menke, Niklas Enderlein, Roland Gillen +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…
Interacting nodal semimetals with non-linear bands
Arianna Poli, Niklas Wagner, Max Fischer +3
We investigate the quasi-particle and transport properties of a model describing interacting Dirac and Weyl semimetals in the presence of local Hubbard repulsion , where we expl…
Thermodynamic Stability at the Two-Particle Level
A. Kowalski, M. Reitner, L. Del Re +6
We show how the stability conditions for a system of interacting fermions that conventionally involve variations of thermodynamic potentials can be rewritten in terms of one- and t…
Dynamical correlations and order in magic-angle twisted bilayer graphene
Gautam Rai, Lorenzo Crippa, Dumitru Călugăru +8
In magic angle twisted bilayer graphene, transport, thermodynamic and spectroscopic experiments pinpoint at a competition between distinct low-energy states with and without electr…
Mott-Hubbard transition in V2O3 revisited
P. Hansmann, A. Toschi, G. Sangiovanni +4
The isostructural metal-insulator transition in Cr-doped V2O3 is the textbook example of a Mott-Hubbard transition between a paramagnetic metal and a paramagnetic insulator. We rev…
