This research paper investigates the correlation-driven charge migration process in adenine after ionization with an attosecond pulse. The study reveals that the production of doubly charged adenine, via a delayed second ionization event, is a signature of a charge inflation mechanism resulting from many-body excitation. This is supported by time-dependent simulations, suggesting potential control of molecular reactivity at the few-femtosecond timescale.
