Many-Body Models\nfor Chirality-Induced Spin Selectivity\nin Electron Transfer

We present the first microscopic model for the chirality-induced\nspin selectivity effect in electron-transfer, in which the internal\ndegrees of freedom of the chiral bridge are explicitly included. By\nexactly solving this model on short chiral chains we demonstrate that\na sizable spin polarization on the acceptor arises from the interplay\nof coherent and incoherent dynamics, with strong electron–electron\ncorrelations yielding many-body states on the bridge as crucial ingredients.\nMoreover, we include the coherent and incoherent dynamics induced\nby interactions with vibrational modes and show that they can play\nan important role in determining the long-time polarized state probed\nin experiments.
