Engineering axion insulator phase in superlattices with inversion symmetry breaking
Rajibul Islam, Sougata Mardanya, Alexander Lau +6
We study theoretically the interplay between magnetism and topology in three-dimensional HgTe/MnTe superlattices stacked along the (001) axis. Our results show the evolution of the…
Orbital order and ferromagnetism in LaMnO3 doped with Ga
C. Autieri, M. Cuoco, G. Cuono +2
We study from first principles the magnetic, electronic, orbital and structural properties of the LaMnO3 doped with gallium replacing the Mn-site. The gallium doping reduces the Ja…
Sign change of the anomalous Hall effect and the anomalous Nernst effect in Weyl semimetal CeAlSi
Md Shahin Alam, Amar Fakhredine, Mujeeb Ahmed +9
We report the anomalous Hall effect (AHE) and the anomalous Nernst effect (ANE) data for the non-collinear Weyl semimetal CeAlSi. The anomalous Hall conductivity (σ_ij^A) was measu…
Unprotected edge modes in quantum spin Hall insulator candidate materials
Nguyen Minh Nguyen, Giuseppe Cuono, Rajibul Islam +3
The experiments in quantum spin Hall insulator candidate materials, such as HgTe/CdTe and InAs/GaSb heterostructures, indicate that in addition to the topologically protected helic…
Emergence of Rashba splitting and spin-valley properties in Janus MoGeSiP2As2 and WGeSiP2As2 monolayers
Ghulam Hussaina, Abdus Samad, Majeed Ur Rehmanc +2
First-principles calculations are performed to study the structural stability and spintronics properties of Janus MoGeSiP2As2 and WGeSiP2As2 monolayers. The high cohesive energies…
Electronic and optical properties of InAs/InAsSb superlattices and their application to far-infrared detectors
Ghulam Hussain, Giuseppe Cuono, Rajibul Islam +4
We calculate the electronic and optical properties of InAs/InAsSb superlattices within relativistic density functional theory. To have a good description of the…
