Analytical results of Typical Medium Theory for the Bethe lattice with Cauchy disorder
A. Östlin, I. Titvinidze, M. Kollar +2
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…
Invisible flat bands on a topological chiral edge
Youjiang Xu, Irakli Titvinidze, Walter Hofstetter
We prove that invisible bands associated with zeros of the single-particle Green's function exist ubiquitously at topological interfaces of 2D Chern insulators, dual to the chiral…
Hubbard model on the kagome lattice with time-reversal invariant flux and spin-orbit coupling
Irakli Titvinidze, Julian Legendre, Karyn Le Hur +1
We study the Hubbard model with time-reversal invariant flux and spin-orbit coupling and position-dependent onsite energies on the kagome lattice, using numerical and analytical me…
Spin-orbit coupling in the kagome lattice with flux and time-reversal symmetry
Irakli Titvinidze, Julian Legendre, Maarten Grothus +3
We study the topological properties of a spin-orbit coupled Hofstadter model on the Kagome lattice. The model is time-reversal invariant and realizes a topological i…
