Tunable Coupling, Topology, and Chirality by Antimagnons in Magnetic Multilayer
Yifan Liu, Zehan Chen, Qiming Shao
Realizing novel topological states in magnonic systems unlocks robust, low-power spin-wave devices. In this letter, we show that incorporating left-handed spin waves (antimagnons)…

Correlation-driven quantum geometry effects in a Kondo system
Ruizi Liu, Zehan Chen, Xingkai Cheng +9
Quantum geometry, including quantum metric and Berry curvature, which describes the topology of electronic states, can induce fascinating physical properties. Symmetry-dependent no…
