      abstract     = {Sudden ionisation of a relatively large molecule can
                      initiate a correlation-driven process dubbed charge
                      migration, where the electron density distribution is
                      expected to rapidly change. Capturing this
                      few-femtosecond/attosecond charge redistribution represents
                      the real-time observation of the electron correlation in the
                      molecule. So far, there has been no experimental evidence of
                      this process. Here we report on a time-resolved study of the
                      correlation-driven charge migration process occurring in the
                      bio-relevant molecule adenine after ionisation by a 15-35 eV
                      attosecond pulse. We find that, the production of intact
                      doubly charged adenine - via a shortly-delayed laser-induced
                      second ionisation event - represents the signature of a
                      charge inflation mechanism resulting from the many-body
                      excitation. This conclusion is supported by first-principles
                      time-dependent simulations. Our findings opens new important
                      perspectives for the control of the molecular reactivity at
                      the electronic timescale.},
