Orbital Hall effect and orbital altermagnetism in even- and odd-parity-wave magnetic Lieb lattices
Börge Göbel, Ersoy Şaşıoğlu, Samir Lounis
Altermagnets combine compensated antiferromagnetic order with ferromagnet-like signatures such as spin-polarized bands and, under appropriate conditions, an anomalous Hall response…

Systematic cRPA study of two-dimensional MAZ materials: From unconventional screening to correlation-driven instabilities
F. Bagherpour, Y. Yekta, H. Hadipour +5
Understanding the interplay between screening, electronic correlations, and collective excitations is essential for the design of two-dimensional quantum materials. Here, we presen…
