Laser-controlled, spin-dependent charge dynamics in molecules is studied with a particular focus on the influence of the topology on the coupled spin-charge time evolution. Methods of ab-initio quantum chemistry, quantum dynamics in intense fields, classical and quantum spin dynamics, and a reductive symmetry analysis render possible a reliable description and a clear picture of the driven spin dynamics in chiral/helical and other molecules in tailored intense fields. Laser fields with engineered helical waves may generate internal orbital currents that we will calculate and utilize to steer in a spatio-temporal way the spin degree of freedom. Furthermore, we will develop and implement a theory for the molecular nonadiabatic tunnel ionization in strong circularly polarized laser fields and explore thereby the spin polarization effects and the role played of the underlying geometric molecular structure.
