Tuning the topological character of half-Heusler systems: A comparative study on YBi ( = Pd, Pt)
J. C. Souza, M. V. Ale Crivillero, H. Dawczak-Dębicki +3
Half-Heusler systems host a plethora of different ground states, especially with non-trivial topology. However, there is still a lack of spectroscopic insight into the correspondin…
Magnetic interactions of 4 electrons in the topological insulator chalcogenide BiSe
J. C. Souza, M. Carlone, G. G. Lesseux +5
The gap opening mechanism of a topological insulator, the quantum anomalous Hall effect and the axion physics are still pressing open questions and a microscopic viewpoint to furth…
Tuning the nontrivial topological properties of the Weyl semimetal CeAlSi
M. M. Piva, J. C. Souza, V. Brousseau-Couture +6
In the ferromagnetic Weyl semimetal CeAlSi both space-inversion and time-reversal symmetries are broken. We use external pressure as an effective tuning parameter and relate three…
Systematic manipulation of the surface conductivity of SmB
M. Victoria Ale Crivillero, M. König, J. C. Souza +5
We show that the resistivity plateau of SmB at low temperature, typically taken as a hallmark of its conducting surface state, can systematically be influenced by different sur…
