Ultrafast quantum beats of anisotropic excitons in atomically thin ReS2

Quantum beats are periodic oscillations originating from the superposition of coherent quantum states. Here, the authors observe exciton quantum beats in the optical spectrum of atomically thin ReS2, and modulate the intensity of the quantum beat signal by means of light polarisation.
