Analytical results of Typical Medium Theory for the Bethe lattice with Cauchy disorder
A. Ãstlin, A. Östlin, I. Titvinidze +3
We present a combined numerical and analytically tractable realization of the typical medium theory (TMT) for Anderson localization on the infinite-connectivity Bethe lattice with…

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…
