Diamagnetic Sm in the topological Kondo insulator SmB
W. T. Fuhrman, J. C. Leiner, J. W. Freeland +5
Samarium hexaboride is a topological Kondo insulator, with metallic surface states manifesting from its insulating band structure. Since the insulating bulk itself is driven by str…
A brief geometric derivation of some fundamental physics
Michel van Veenendaal
Several fundamental results in physics are derived from the simple starting point of two commuting orthogonal unit vectors. The combination of these unit vectors leads to spherical…
Origin of Strong Dispersion in Hubbard Insulators
Yao Wang, Krzysztof Wohlfeld, Brian Moritz +5
Using cluster perturbation theory, we explain the origin of the strongly dispersive feature found at high binding energy in the spectral function of the Hubbard model. By comparing…
Evolution of Electronic Structure Across the Rare-Earth RNiO Series
John W. Freeland, Michel van Veenendaal, Jak Chakhalian
The perovksite rare-earth nickelates, RNiO (R=La ... Lu), are a class of materials displaying a rich phase-diagram of metallic and insulating phases associated with charge and…
Spin chain in magnetic field: limitations of the large-N mean-field theory
Krzysztof Wohlfeld, Cheng-Chien Chen, Michel van Veenendaal +1
Motivated by the recent success in describing the spin and orbital spectrum of a spin-orbital chain using a large-N mean-field approximation [Phys. Rev. B 91, 165102 (2015)], we ap…
Effective transition operators for resonant inelastic X-ray scattering
Michel van Veenendaal
Effective symmetry-based transition operators for resonant inelastic X-ray scattering (RIXS) are derived that show how the scattering between different states depends on the polari…
