In this seminar, Mr. Tingyu Zhang presented their work on spin transport phenomena at strongly-correlated interfaces. They study the spin tunneling in a repulsively interacting ultracold Fermi gas based on the conventional quasiparticle tunneling process. The change of the Fano factor microscopically evinces a crossover from the quasiparticle transport to magnon transport in itinerant fermionic systems.
