Flat Bands at the Fermi Level in Unconventional Superconductor YFe2Ge2
R. Kurleto, C. -H. Wu, S. Acharya +15
We report heavy electron behavior in unconventional superconductor YFeGe ( K). We directly observe very heavy bands () within $\…
Lattice fluctuations, not excitonic correlations, mediated electronic localization in TiSe
Ross E. Larsen, Dimitar Pashov, Matthew D. Watson +2
TiSe is thought to be an insulator with a bandgap of ~0.1eV. It has attracted a much interest because, among of a rich array of unique properties, many have thought TiSe is…
Pb-apatite framework as a generator of novel flat-band CuO based physics
Rafal Kurleto, Stephan Lany, Dimitar Pashov +3
Based on DFT calculations, we present the basic electronic structure of CuPb9(PO4)6O (Cu-doped lead apatite, LK-99), in two scenarios: (1) where the structure is constrained to the…
Multiple Slater determinants and strong spin-fluctuations as key ingredients of the electronic structure of electron- and hole-doped PbCu(PO4)O
Dimitar Pashov, Swagata Acharya, Stephan Lany +2
LK-99, with chemical formula PbCu(PO4)O, was recently reported to be a room-temperature superconductor. While this claim has met with little support in a flurry of…
One-particle and excitonic band structure in cubic Boron Arsenide
Swagata Acharya, Dimitar Pashov, Mikhail I Katsnelson +1
Cubic BAs has received recent attention for its large electron and hole mobilities and large thermal conductivity. This is a rare and much desired combination in semiconductor indu…
Paramagnetic Electronic Structure of CrSBr: Comparison between Ab Initio GW Theory and Angle-Resolved Photoemission Spectroscopy
Marco Bianchi, Swagata Acharya, Florian Dirnberger +9
We explore the electronic structure of paramagnetic CrSBr by comparative first principles calculations and angle-resolved photoemission spectroscopy. We theoretically approximate t…
