| 报告介绍 | 报告摘要：
The response of molecules to sequences of ultrafast optical pulses ranging from the infrared to the hard x-ray regimes provides novel windows into elementary molecular events and electronic and nuclear motions. Recent developments in this field involving the use of broadband x-ray pulses and entangled photons will be surveyed. New x-ray light sources are capable of triggering valence electron motions impulsively by a stimulated resonant Raman process via core excitations and monitoring them with high temporal and spatial resolution. A new technique TRUE-CARS, Transient Redistribution of Ultrafast Electronic Coherences in Attosecond Raman Signals, that can detect the passage through a COIS is presented. Quantum spectroscopy signals are recorded by varying parameters of the photon wavefunction rather than classical field envelopes. The unusual spectral and temporal characteristics of entangled photon pairs combined with interferometric detection make it possible to manipulate and control multiple exciton states in photosynthetic reaction centers.
