Production of angular momentum in helical molecular wires under electric current
at 13:00 in Seminar room F052

Various spin-selective phenomena have been recently reported for helical molecular wires. The explanation of these phenomena is still lacking [1]. I will present a theoretical analysis of spin currents in non-magnetic molecular junctions. First, constraints based on time- reversal invariance will be summarized. Second, I will present results based on Landauer formalism and simple model Hamiltonians [2]. Possible experimental detection setups will be discussed. If time permits, I will discuss the production of mechanical angular momentum in molecular rotors based on either local momentum transfer or spin-orbit coupling [3].
