Accessing quasi-flat -bands to harvest large Berry curvature in NdGaSi
Anyesh Saraswati, Jyotirmoy Sau, Vera Misheneva +10
In typical rare-earth lanthanide compounds, the localized 4\textit{f}-electrons have a weak effect on the electrical conduction, limiting their influence on the Berry curvature and…
Identifying open-orbit topological surface states in dual topological semimetal TaSb
Susmita Changdar, Heike Schlörb, Oleksandr Suvorov +8
TaSb, a member of the transition metal dipnictide family of materials, hosts the very rare dual topological phase - weak topological insulating state and topological crystallin…
Three prerequisites for high-temperature superconductivity in t-PtBi
Andrii Kuibarov, Susmita Changdar, Riccardo Vocaturo +9
Although the generic mechanism behind high-temperature superconductivity remains notoriously elusive, a set of favorable conditions for its occurrence in a given material has emerg…
Measuring superconducting arcs by ARPES
Andrii Kuibarov, Susmita Changdar, Alexander Fedorov +8
Angle-resolved photoemission spectroscopy is the leading tool for studying the symmetry and structure of the order parameter in superconductors. The recent improvement of the techn…
Orbital-selective effect of spin reorientation on the Dirac fermions in a non-charge-ordered kagome ferromagnet FeGe
Rui Lou, Liqin Zhou, Wenhua Song +13
Kagome magnets provide a fascinating platform for the realization of correlated topological quantum phases under various magnetic ground states. However, the effect of the magnetic…
