Analytic density of states of two-dimensional Chern insulator
Vera Uzunova, Krzysztof Byczuk
We present analytic expressions for the density of states and its consistent derivation for the two-dimensional Qi-Wu-Zhang (QWZ) Hamiltonian, a generic model for the Chern topolog…
Topological Mott insulator in the odd-integer filled Anderson lattice model with Hatsugai-Kohmoto interactions
Krystian Jabłonowski, Jan Skolimowski, Wojciech Brzezicki +2
Recently, a quantum anomalous Hall state at odd integer filling in moiré stacked MoTe/WSe was convincingly interpreted as a topological Mott insulator state appearing due t…
Impurities and other defects in correlated lattice electrons: Friedel oscillations and interference patterns
Banhi Chatterjee, Jan Skolimowski, Krzysztof Byczuk
We study interference patterns and Friedel oscillations (FO) due to scattering from two or more localized impurities and scattering from extended inhomogeneities in the two-dimensi…
Ab initio typical medium theory of substitutional disorder
A. Östlin, Y. Zhang, H. Terletska +7
By merging single-site typical medium theory with density functional theory we introduce a self-consistent framework for electronic structure calculations of materials with substit…
Real-space dynamical mean-field theory of Friedel oscillations in strongly correlated electron systems
B. Chatterjee, J. Skolimowski, K. Makuch +1
We study Friedel oscillations and screening effects of the impurity potential in the Hubbard model. Electronic correlations are accounted for by solving the real-space dynamical me…
T-matrix formulation of real-space dynamical mean-field theory and the Friedel sum rule for correlated lattice fermions
K. Byczuk, B. Chatterjee, D. Vollhardt
We formulate real-space dynamical mean-field theory within scattering theory. Thereby the Friedel sum rule is derived for interacting lattice fermions at zero temperature.
