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…
Orbital Magnetic Field Driven Metal-Insulator Transition in Strongly Correlated Electron Systems
Georg Rohringer, Anton A. Markov
We study the effects of an orbital magnetic field on the Mott metal-insulator transition in the Hubbard-Hofstadter model. We demonstrate that sufficiently large magnetic fields ind…
Suppression of the charge fluctuations by nonlocal correlations close to the Mott transition
Irakli Titvinidze, Julian Stobbe, Marvin Leusch +1
In this paper, we investigate the impact of nonlocal correlations on charge fluctuations in the two-dimensional single-band Hubbard model close to the Mott metal-to-insulator trans…
Mean Field Decoupling of Single Impurity Anderson Model through Auxiliary Majorana Fermions
Irakli Titvinidze, Julian Stobbe, Alexey N. Rubtsov +1
We present a method to study the time evolution of the single impurity Anderson model which exploits a mean field decoupling of the interacting impurity and the non-interacting bat…
