Signatures of Chiral Phonons in MnPS from first principles
Banhi Chatterjee, Peter Kratzer
Two-dimensional (2D) materials may host circular phonons, considered as chiral if the presence of a substrate breaks mirror symmetry. In 2D transition metal dichalcogenide (TMDC) m…
Collective modes and Raman response in TaNiSe
Banhi Chatterjee, Jernej Mravlje, Denis Golež
We explore the collective response in an excitonic insulator phase in TaNiSe using a semirealistic model including relevant lattice and electronic instabilities. We calcula…
Electronic structure and magnetism in UGa2: DFT+DMFT approach
Banhi Chatterjee, Jindrich Kolorenc
The debate whether uranium 5f electrons are closer to being localized or itinerant in the ferromagnetic compound UGa2 is not yet fully settled. The experimentally determined magnet…
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…
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.
