a, Time-resolved computed HSB emission intensity for monolayer (blue line) and bulk (orange line) WSe2. Coherent excitons are created by an 8.6 fs NIR pulse (intensity envelope, red line) at time tex after the peak of the THz field (|ETHz|, grey shaded area). The HSB emission peaks (vertical dashed lines) at \({T}_{{\rm{coll}}}^{{\rm{ML}}}\) = 12.6 fs after the excitation for monolayer and at \({T}_{{\rm{coll}}}^{{\rm{bulk}}}\) = 18.6 fs for bulk WSe2, respectively. b–e, HSB Wigner functions WHSB(x,k) (contours) at times t = 12.6 fs and t = 18.6 fs for monolayer and bulk WSe2. Orange lines show the dynamics of the centroid of the Wigner function.
