Magnetically tunable symmetry-enforced nodal lines producing huge anomalous Hall conductivity in altermagnetic -MnTe
Mathews Benny, Xujia Gong, Amar Fakhredine +21
Altermagnetic -MnTe exhibits huge anomalous Hall conductivity (AHC) up to room-temperature together with weak ferromagnetism arising from spin and orbital polarizations. We clar…
Effect of polar distortions on the linear and nonlinear anomalous Hall conductivity of altermagnetic -MnTe
Mathews Benny, Sahar Izadi Vishkayi, Amar Fakhredine +2
Altermagnetic -MnTe with Néel vector along the -axis exhibits a finite anomalous Hall conductivity (AHC) and weak ferromagnetism along the -axis. As already demonstrated i…
Symmetry-protected nodal planes and accidental nodal surfaces in mixed odd-even wave spin-momentum locking of relativistic altermagnets
Xujia Gong, Amar Fakhredine, Sahar Izadi Vishkayi +1
Non-relativistic spin--momentum locking in altermagnets exhibits an even number of nodal planes. In the relativistic limit, the number of nodal planes can be lowered by symmetry re…
Kagome goldene with flat bands and Dirac nodal line fermions via line-graph epitaxy
Qiwei Tian, Sahar Izadi Vishkayi, Chen Zhang +8
The kagome lattice has emerged as a promising platform for investigating exotic quantum phases. However, achieving a single-atomic-layer kagome lattice in elemental materials remai…
Origin and properties of the flat band in NbOCl2 monolayer
Mohammad Ali Mohebpour, Sahar Izadi Vishkayi, Valerio Vitale +2
The existence of a flat band near the Fermi level can be a suitable platform for the emergence of interesting phenomena in condensed matter physics. Recently, NbOCl2 monolayer has…
