Decoherence and Revival of Attosecond Charge Migration Driven by Non-adiabatic Dynamics

The attosecond quantum beat of an electronic state superposition was captured in SiH4 using soft-X-Ray attosecond transient-absorption spectroscopy. Its decoher-ence and revival, induced by non-adiabatic vibrational dynamics, were reproduced using MCTDH calculations.
