Spin-wave dynamics controlled by tunable ac magnonic crystal
Ankang Liu, Alexander M. Finkel'stein
The magnonic crystal, which has a spatial modulation wave vector , couples the spin wave with wave vector to the one with wave vector . For a conventional magnonic crys…

Spin waves in layered antiferromagnets with honeycomb structure
Ankang Liu, Alexander M. Finkel'stein
We develop a description of spin waves in a quantum antiferromagnet (AFM) in terms of macroscopic variables, magnetization and Néel vector densities. We consider a layere…
