We are looking for qualified candidates to work on the following 2 PhD projects at the interface of terahertz spin-orbitronics and ultrafast transport:

  1. Ultrafast transport of electron orbital angular momentum in spin-orbitronic multilayers
    https://www.fu-berlin.de/universitaet/beruf-karriere/jobs/english/PH-2503-AG-Kampfrath-WiMi-ORB1_E.html

  2. Novel terahertz emitters based on ultrafast currents in anisotropic nanostructures
    https://www.fu-berlin.de/universitaet/beruf-karriere/jobs/english/PH-2502-AG-Kampfrath-WiMi-ACEs_E.html

Both projects use a common, quite unique methodology: (i) We induce ultrafast transport by femtosecond laser pulses and time-resolve the transport dynamics by the terahertz electromagnetic radiation that is emitted by the transport. (ii) We use intense terahertz electric or magnetic fields to drive transport. We detect their action by a time-delayed, ultrashort and highly sensitive (magneto-)optic probe pulse.

In the two projects, this methodology, along with detailed analysis and modeling, is used to address different materials and questions.

  1. Spin-orbitronics: The goal is to understand the transport dynamics of electron orbital angular momentum on the fastest time scales. How can we generate such orbital currents efficiently? How do they propagate and decay? How can we use them to exert torque on magnetization of a ferromagnet and potentially even write information?

  2. Anisotropic-conductivity materials: We want to understand how ultrafast electron transport proceeds in materials with highly anisotropic conductivity. How does the transport dynamics depends on the direction of the ultrafast electron current? By which force is it driven microscopically? How can we use this effect to build efficient generators of terahertz electromagnetic pulses?
