In this thesis we investigate the interplay between quantum transport of coherent electrons and collective modes. We consider both vibrational modes in nanoelectromechanical systems and localized spin degrees of freedom in single- molecule junctions. This field has attracted considerable interest for reasons of basic research and for possible applications in nanoelectronics. This thesis focuses on the regime in which the collective modes are slowly varying on the typical time scale of the electrons. While the latter observe a quasistatic configuration, justifying the use of a non-equilibrium Born- Oppenheimer approximation (NEBO), they can affect the collective modes significantly through current induced forces. Within this approach we stud...
