Transient optical spectroscopy on twisted molybdenum ditelluride reveals nearly 20 hidden states at fractional fillings that are absent in static optical sensing or transport measurements, giving insight into novel vibronic coupling of correlated states.

Reflection and photoluminescence spectroscopy measurements reveal sharp shifts in excitonic spectra at different critical electric fields, arising from lateral displacements between the layers. This uniquely controllable phenomenon will advance future investigations of anharmonic vibronic coupling.

Reflectance spectroscopy reveals that an electric field distorts valence-band Bloch states in bilayer semiconductor devices, driving the hole wavefunction from one layer to the other. Such wavefunction engineering is being explored to engineer exciton-vibrational coupling.

We establish an ultrafast photodoping mechanism in the moiré bilayer from photo-thermionic emission of the graphite gates. Using transient reflectance experiments, we reveal photo-induced hole injection, a novel ultrafast transport probe for future work on vibronics in energy and time.
