Coherent Interaction of 2s and 1s Exciton States in Transition-Metal Dichalcogenide Monolayers

Max Wegerhoff, Moritz Scharfstädt, Stefan Linden +1

We use femtosecond pump-probe spectroscopy to study the coherent interaction of excited exciton states in WSe2 and MoSe2 monolayers via the optical Stark effect. For co-circularly…
