Query: Probing dephasing time of crystals via spectral properties of
  high-harmonic generation   Coherent time is a characteristic time in the extreme nonlinear optics regime
and thus generally introduced as the dephasing time in the simulations of the
solid-state high-harmonic generation. This characteristic time linked with the
coherent decay of quantum trajectory controls the emergence of the spectral
splittings in the high harmonic spectroscopy, which can been attributed to the
temporal interference between two adjacent harmonic emission channels. To
reproduce the harmonic peaks and spectral splittings, a temporal two-slit
interference model in the momentum space is introduced. In addition, mechanisms
of spectral splitting provide a state-of-the-art avenue to probe the
characteristic elapse between electron and hole. Based on the subfemtosecond
resolution of the spectral interference opening and closing zones in the
wavelength-dependent high-order harmonic spectra, we also propose an
alternative scheme to probe the dephasing time of crystals by the feasible
laser pulses in present experimental setups.
