Correlation-driven sub-3 fs charge migration in ionised adenine
Erik P. Mansson, Simone Latini, Fabio Covito +15
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 c…
Efficient computation of the second-Born self-energy using tensor-contraction operations
Riku Tuovinen, Fabio Covito, Michael A. Sentef
In the nonequilibrium Green's function approach, the approximation of the correlation self-energy at the second-Born level is of particular interest, since it allows for a maximal…
Benchmarking Nonequilibrium Green's Functions against Configuration Interaction for time-dependent Auger decay processes
F. Covito, E. Perfetto, A. Rubio +1
We have recently proposed a Nonequilibrium Green's Function (NEGF) approach to include Auger decay processes in the ultrafast charge dynamics of photoionized molecules. Within the…
Real-time dynamics of Auger wavepackets and decays in ultrafast charge migration processes
F. Covito, E. Perfetto, A. Rubio +1
The Auger decay is a relevant recombination channel during the first few femtoseconds of molecular targets impinged by attosecond XUV or soft X-ray pulses. Including this mechanism…
