Realizing Novel Phases of Materials with Light-Matter Interaction
Abstract
The purpose of the proposed research is to investigate whether Floquet-Bloch states induced by light fields can be used to engineer materials with distinct properties. Specific objectives include the observation of a light-induced (i) quantum anomolous Hall effect in graphene, (ii) topological state in MoS2, and (iii) modified exchange interactions in correlated oxides. Mid-infrared laser pulses will be used to excite materials into Floquet-Bloch states. Time-resolved and angle-resolved photoemission spectroscopy (trARPES) and THz spectroscopy will be used to probe the materials before, during and after the laser pulses. The materials to be studied include graphene, MoS2 and several oxides.
