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…
Chiral Magnons and Cycloidal Phonons in Altermagnetic CuF Monolayer
Andrea M. León, MatÃas F. Torreblanca, Carmine Autieri +1
Altermagnetism establishes momentum-dependent spin splitting through non-symmorphic crystal symmetries, yet whether these same symmetries simultaneously govern spin and lattice col…
Berry-Curvature Activation by Orbital Flux in a Kagome Altermagnet
Meysam Bagheri Tagani, Carmine Autieri
We investigate topological electronic responses in a kagome altermagnetic metal hosting a compensated coplanar magnetic texture. Using a minimal tight-binding model con…
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…
Contemporary Insights into Electronic Structure and Microscopic Transport in Nodal-Line Semimetals
Ashutosh S. Wadge, Pardeep K. Tanwar, Giuseppe Cuono +1
Topological semimetals have emerged as an important class of quantum materials with novel electronic responses and unconventional transport phenomena. Among them, nodal-line semime…
Long-Lived Interlayer Excitons and Type-II Band Alignment in Janus MoTe2/CrSBr van der Waals Heterostructures
Mohammad Ali Mohebpour, Peter C Sherrell, Catherine Stampfl +2
Identifying two-dimensional heterostructures with exceptional electronic and optical properties remains an active area of research in advanced optoelectronics. Here, we present a c…
