Electronic Structure of Chromium Trihalides beyond Density Functional Theory

Swagata Acharya, Dimitar Pashov, Brian Cunningham +5

We explore the electronic band structure of free standing monolayers of chromium trihalides, CrX\textsubscript{3}{, X= Cl, Br, I}, within an advanced \emph{ab-initio} theoretical a…

Environmental Screening and Ligand-Field Effects to Magnetism in CrI Monolayer

D. Soriano, A. N. Rudenko, M. I. Katsnelson +1

We present a detailed study on the microscopic origin of magnetism in suspended and dielectrically embedded CrI monolayer. To this end, we down-fold two distinct minimal genera…

Random Phase Approximation for gapped systems: role of vertex corrections and applicability of the constrained random phase approximation

Erik G. C. P. van Loon, Malte Rösner, Mikhail I. Katsnelson +1

The many-body theory of interacting electrons poses an intrinsically difficult problem that requires simplifying assumptions. For the determination of electronic screening properti…

Introducing strong correlation effects into graphene by gadolinium intercalation

S. Link, S. Forti, A. Stöhr +11

Exotic ordered ground states driven by electronic correlations are expected to be induced in monolayer graphene when doped to the Van Hove singularity. Such doping levels are reach…

Internal screening and dielectric engineering in magic-angle twisted bilayer graphene

J. M. Pizarro, M. Rösner, R. Thomale +2

Magic-angle twisted bilayer graphene (MA-tBLG) has appeared as a tunable testing ground to investigate the conspiracy of electronic interactions, band structure, and lattice degree…

Electronic structure of single layer 1T-NbSe: interplay of lattice distortions, non-local exchange, and Mott-Hubbard correlations

E. Kamil, J. Berges, G. Schönhoff +4

Using ab-initio calculations we reveal the nature of the insulating phase recently found experimentally in monolayer 1T-NbSe. We find soft phonon modes in a large parts of the…
