Paper Abstract

Monolayer transition metal dichalcogenides present the opportunity to manipulate quantum states of matter via ultrafast laser pulses, permitting, for example, observation of the phase transition from trivial to topological insulator. However, the nature of ultrafast pulses are far removed from the theoretical assumptions used to model these phenomena. We have used ultrafast pump-probe spectroscopy to observe the influence of an ultrashort laser pulse on the coherent response of monolayers of MoS2 and WS2 to investigate how an ultrashort pulse may cause the system to deviate from the behaviour expected from theoretical predictions.
