Towards Measuring Attochemical Processes in Condensed Phase Neutral Species

Developments in attosecond science have provided avenues for chemical processes to be studied on the timescale of pure electronic dynamics. Early experiments in gas phase atomic and small molecule systems showed that using an attosecond duration laser pulse to directly photoionize a system can create a superposition of many cationic states which enable charge migration to occur through coherence and/or correlation. These experiments have driven further experimental and theoretical investigations to understand the chemical factors governing electronic charge migration on the attosecond and few-femtosecond timescale, such as to what extent the system nuclei or environment perturb charge migration. This talk will focus on bringing the ideas of attochemistry into the realm of condensed phase neutral species, where the distinctions between pure electron interactions, electron-electron correlation, and electronic-vibrational correlations are central for understanding the boundaries between charge migration and charge transfer to measure attochemistry in condensed phases. The lastest results of Co-CN-Fe systems will be discussed with developments in new nonlinear tabletop attosecond experiments.
