Circular phonon dichroism in -wave altermagnets
Ding Li, Tao Qin, Jianhui Zhou
Altermagnets, a new class of collinear antiferromagnets, exhibit momentum-dependent spin splitting and offer compelling advantages for antiferromagnetic spintronics. However, the m…
Universal classes of disorder scatterings in in-plane anomalous Hall effect
Guoao Yang, Tao Qin, Jianhui Zhou
The in-plane anomalous Hall effect (IPAHE) with planar Hall current and magnetization/magnetic fields in various quantum materials has received increasing attention. Most of the cu…
Phonon Dichroisms Revealing Unusual Electronic Quantum Geometry
Ding Li, Guoao Yang, Tao Qin +2
The quantum geometry tensor, intrinsic geometric characteristics of electronic states, plays a crucial role in the various nontrivial electromagnetic phenomena in quantum materials…
Many-body multipole indices revealed by the real-space dynamical mean-field theory
Guoao Yang, Jianhui Zhou, Tao Qin
The multipole moments are fundamental properties of insulators, and have attracted lots of attention with emerging of the higher-order topological insulators. A couple of ways, inc…
