Optical conductivity and band gap in the double-Weyl candidate SrSi2 at ambient pressure
L. Z. Maulana, A. A. Tsirlin, E. Uykur +4
We probe the possible double-Weyl state in cubic SrSi2 using optical spectroscopy. The complex optical conductivity was measured in a frequency range from 70 to 22 000 cm-1 at temp…

Interlayer charge transfer induced by electronic instabilities in the natural van der Waals hetrostructure 4H-TaS
R. Mathew Roy, X. Feng, M. Wenzel +6
The natural van der Waals heterostructure 4H-TaS composed of alternating 1T- and 1H-TaS layers serves as a platform for investigating the electronic correlations and la…

Intriguing Low-Temperature Phase in the Antiferromagnetic Kagome Metal FeGe
M. Wenzel, E. Uykur, A. A. Tsirlin +7
The properties of kagome metals are governed by the interdependence of band topology and electronic correlations resulting in remarkably rich phase diagrams. Here, we study the tem…
