Published: Ultrafast broadband optical spectroscopy for quantifying subpicometric coherent atomic displacements in WTe2

Here we show how time-resolved broadband optical spectroscopy can be used to quantify, with femtometer resolution, the oscillation amplitudes of coherent phonons through a displacive model without free tuning parameters, except an overall scaling factor determined by comparison between experimental data and DFT calculations.
