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…
Extremely Large and Angle-Dependent Magnetoresistance in Kagome Dirac Semimetal RFeSn (R=Ho, Dy)
Susanta Ghosh, Achintya Low, Nayana Devaraj +3
We report on the electronic, magnetic, and magneto-transport properties of Fe-based kagome Dirac system, RFeSn (R = Ho, Dy). Magnetic properties study reveals an antiferrom…
Topological nodal -wave superconductivity in PtBi
Susmita Changdar, Oleksandr Suvorov, Andrii Kuibarov +11
Most superconducting materials are well-understood and conventional in the sense that the pairs of electrons that cause the superconductivity by their condensation have the highest…
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…
Topological Hall effect in ferromagnetic Weyl semimetal MnGe originating in competing dipolar interaction and magnetocrystalline anisotropy
Achintya Low, Tushar Kanti Bhowmik, Susanta Ghosh +2
We report the anomalous and topological Hall effect of the ferromagnetic Weyl semimetal MnGe. We observe a significant anisotropic anomalous Hall effect (AHE) due to nonzer…
