We present a model of the attosecond resonant dynamics of valence electron photoemission and MMM Auger electron emission in copper dichloride. At τhâ‰1/ωIR (where τh is the core-hole relaxation time and ωIR is the energy of the infrared probe field), high-order Fano sideband resonances on both sides of the original (zeroth-order) resonance are found in the energy domain on the time scale of τh. This is confirmed by a coherent π rotation of the relative phase between the photoelectron and Auger electron at each resonance, due to the subfemtosecond quantum correlation. We also find a core-hole clock, the asymmetry factor q of the first-order Fano sideband resonance, which can directly trace the core-hole relaxation in the time domain. © 2013 American Physical Society.
