Floquet engineering of Kitaev quantum magnets
Umesh Kumar, Saikat Banerjee, Shi-Zeng Lin
In recent years, there has been an intense search for materials realizing the Kitaev quantum spin liquid model. A number of edge-shared compounds with strong spin-orbit coupling, s…

Inverse Faraday effect in Mott insulators
Saikat Banerjee, Umesh Kumar, Shi-Zeng Lin
The inverse Faraday effect (IFE), where a static magnetization is induced by circularly polarized light, offers a promising route to ultrafast control of spin states. Here we study…
