Real-time observation of a correlation-driven sub 3 fs charge migration in ionised adenine

E. P. Månsson, S. Latini, et al.

This groundbreaking research conducted by Erik P Månsson and team uncovers the fascinating charge migration process in adenine following ionization with an attosecond pulse. Their findings reveal that the delayed second ionization leading to doubly charged adenine could provide a novel method for manipulating molecular reactivity at extraordinarily short timescales.

Abstract

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.
