We report measurement of terahertz anomalous Hall conductivity and Faraday rotation in the magnetic Weyl semimetal CoMnGa thin films as a function of the magnetic field, temper…
Kondo physics in antiferromagnetic Weyl semimetal Mn3+xSn1-x films
Durga Khadka, T. R. Thapaliya, Sebastian Hurtado Parra +9
Topology and strong electron correlations are crucial ingredients in emerging quantum materials, yet their intersection in experimental systems has been relatively limited to date.…
Electron-Hole Asymmetry of Surface States in Topological Insulator Sb2Te3 Thin Films Revealed by Magneto-Infrared Spectroscopy
Yuxuan Jiang, Mahmoud M. Asmar, Xingyue Han +7
When surface states (SSs) form in topological insulators (TIs), they inherit the properties of bulk bands, including the electron-hole (e-h) asymmetry but with much more profound i…
