Laser control of magnonic topological phases in antiferromagnets

Nakata, Koki ; Kim, S. K.*; Takayoshi, Shintaro*

We study the laser control of magnon topological phases induced by the Aharonov-Casher effect in insulating antiferromagnets (AFs). Using Floquet formalism, we study nonequilibrium magnon dynamics away from the adiabatic limit and its effect on topological phenomena. Our results provide a handle to control and design magnon topological properties in the insulating AF, and thus open a new door to "photonic magnonics".
