The High-Performance Computing Center Stuttgart (HLRS) showcased the motivation and findings of project A4 in the ICRC TRR 160 in a popular science article. The group lead by Prof. Götz S. Uhrig uses the supercomputer HAWK to simulate the interaction of single electron spins with a large number of nuclear spins in semiconductor quantum dots.

The article highlights the synchronization of the electron spins to a pulsed laser source. Together with the experimental findings in project A1, the simulations allow to enhance the understanding of a coupled electron-nuclear spin system.
