Interplay between altermagnetism and nonsymmorphic symmetries generating large anomalous Hall conductivity by semi-Dirac points induced anticrossings
Amar Fakhredine, Raghottam M. Sattigeri, Giuseppe Cuono +1
We investigate the interplay between altermagnetic spin-splitting and nonsymmorphic symmetries using the space group no. 62 as a testbed. Studying different magnetic orders by mean…
Correlation-driven topological transition in Janus VSiGeP2As2
Ghulam Hussain, Amar Fakhredine, Rajibul Islam +3
The appearance of intrinsic ferromagnetism in 2D materials opens the possibility of investigating the interplay between magnetism and topology. The magnetic anisotropy energy (MAE)…
Interfacial Dzyaloshinskii-Moriya interaction in epitaxial W/Co/Pt multilayers
Sukanta Kumar Jena, Rajibul Islam, Ewelina Milińska +8
Dzyaloshinskii-Moriya interaction (DMI) manifesting in asymmetric layered ferromagnetic films gives rise to non-colinear spin structures stabilizing magnetization configurations wi…
Topological transition in Pb1-xSnxSe using Meta-GGA
Rajibul Islam, Giuseppe Cuono, Nguyen M. Nguyen +2
We calculate the mirror Chern number (MCN) and the band gap for the alloy Pb1-xSnxSe as a function of the concentration x by using virtual crystalline approximation. We use the ele…
Topological phase diagram of Pb1-xSnxSe1-yTey
Giuseppe Cuono, Ghulam Hussain, Amar Fakhredine +1
We reproduce the mirror Chern number phase diagram for the quaternary compound Pb1-xSnxSe1-yTey combining accurate density functional theory and tight-biding model. The tight bindi…
Topological states in superlattices of HgTe-class materials for engineering three-dimensional flat bands
Rajibul Islam, Barun Ghosh, Giuseppe Cuono +7
In search of materials with three-dimensional flat band dispersions, using {\em ab-initio} computations, we investigate how topological phases evolve as a function of hydrostatic p…
