GW-EOS WG Seminar by Pierbiagio Pieri on November 6, 2025

In this seminar, pairing phenomena in three kinds of quantum many-body systems were discussed. First, the speaker reviewed his work on the Bose-Fermi mixture, mainly focusing on the quasiparticles called Fermi-polarons. Second, inhomogeneous pairing fluctuations in a spin-polarized Fermi-Fermi mixture are reviewed. Finally, dissipations called mutual friction arising from interplay between Andreev bound states in the vortex core and delocalized thermal excitations were discussed for strongly interacting Fermi superfluids.
