Photoinduced dynamics of organic molecules using nonequilibrium Green's functions with second-Born, <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:mi>G</mml:mi><mml:mi>W</mml:mi></mml:mrow><mml:mo>,</mml:mo><mml:mo> </mml:mo><mml:mi>T</mml:mi></mml:math> -matrix, and three-particle correlations
The ultrafast hole dynamics triggered by the photoexcitation of molecular targets is a highly correlated process even for those systems, such as organic molecules, having a weakly correlated ground state. We provide a unifying framework and a numerically efficient matrix formulation of state-of-the-art nonequilibrium Green's function (NEGF) methods such as …
