Downfolding from Ab Initio to Interacting Model Hamiltonians: Comprehensive Analysis and Benchmarking of the DFT+cRPA Approach

Yueqing Chang, Erik G. C. P. van Loon, Brandon Eskridge +8

Model Hamiltonians are regularly derived from first-principles data to describe correlated matter. However, the standard methods for this contain a number of largely unexplored app…

Unconventional charge-density-wave gap in monolayer NbS

Timo Knispel, Jan Berges, Arne Schobert +5

Using scanning tunneling microscopy and spectroscopy, for a monolayer of transition metal dichalcogenide H-NbS grown by molecular beam epitaxy on graphene, we provide unambiguo…

Dual Bethe-Salpeter equation for the multi-orbital lattice susceptibility within dynamical mean-field theory

Erik G. C. P. van Loon, Hugo U. R. Strand

Dynamical mean-field theory describes the impact of strong local correlation effects in many-electron systems. While the single-particle spectral function is directly obtained with…

NbCl: A Prototypical Layered Mott-Hubbard Insulator

Sergii Grytsiuk, Mikhail I. Katsnelson, Erik G. C. P. van Loon +1

The Hubbard model provides an idealized description of electronic correlations in solids. Despite its simplicity, the model features a competition between several different phases…

Larmor precession in strongly correlated itinerant electron systems

Erik G. C. P. van Loon, Hugo U. R. Strand

Many-electron systems undergo a collective Larmor precession in the presence of a magnetic field. In a paramagnetic metal, the resulting spin wave provides insight into the correla…
