Tunneling spectroscopy reveals Hund-induced superdispersion in Sr2RuO4, matching DFT+DMFT predictions via non-monotonic real-part self-energy.
For the 1D SU(N) Fermi-Hubbard chain at filling 1/N, the author finds finite critical interactions Uc approximately 1.9, 2.2, 2.8 for N=3, 4, 6, and central charges consistent with N-1 (Mott) and N (metallic) critical modes.
Symmetric TDVP on GPUs achieves converged 1D Fermi-Hubbard quench dynamics at chi~62000 up to t=7, certifying the high-entanglement regime and lowering the reported quantum advantage to ~36x.
