Design of ICRC initiative

Positive indications

Identification of „coherent spin-optronics“ as prospective research field

  • Demand for exploring & demonstrating novel coherent & quantum functionalities
  • Promise: Fast operation & superior performance at low energy dissipation
  • Extension of semiconductor material basis toward hybrid structures
  • Heterovalent semiconductors, combination with metals, etc.
  • Huge advances in manipulation tools (laser & microwave sources, detectors etc.)
  • Adoption of methodology from other areas such as quantum optics

Towards „coherent spin-optronics“ in St.-Petersburg & Dortmund:

  • Thematic expansion by related research topics & techniques
  • Installation of experimental infrastructure
  • Close collaboration for more than 10 years
  • Presence & recognition within scientific community

Design of ICRC initiative


Synergy through complementarity

Theory: semiconductor (SPb) vs many-particle (Do)

focus on time-resolved methods in Do, cw methods at Ioffe
but: also common methodology basis such as spin noise, NMR&ESR, ...

Technology - epitaxy:
GaAs-based (RUB) & ZnSe:F (PB) vs nitride wide gap and antimonides (SPb)


Synchrotron radiation (Do) vs electron microscopy (SPb, support)

Building block 1:

Coherent manipulation:

Toolbox for performing coherent operations


  • Development of elaborated spin control protocols bylaser & microwave pulses

  • Design of spin-spin interactions for maximum robustness

  • Dynamic decoupling: Suppression of perturbations by surrounding noise baths

  • Development of novel spin manipulation tools such as ultrafast acoustics, all-optical imprinting of potential landscapes, etc
