Vorträge von Dr.-Ing. Alon Ascoli (TU Dresden, Fak. Elektrotechnik u. Informationstechnik) und Dipl.-Phys. Matthias Geyer (TU Dresden, Fak. Maschinenwesen) Abstract Matthias Geyer: Various experiments have shown strong spin selectivity in chiral molecules like DNA at room temperature. Since atomic spin orbit coupling alone is insufficient to explain the effect’s magnitude, a relation to the helical geometry has been suggested. We follow two complementary approaches to better understand the underlying mechanisms: To study the influence of the helical geometry we derive an effective 1D Hamiltonian as the adiabatic approximation of a 3D continuum model with helix-shaped confinement. To investigate the effect in a more realistic setting, we perform transport calculations on an effective tight-binding model for Helicene derived from a microscopic model via decimation.
