An efficient method to extract higher-order density-matrix functionals and access operator entanglement is introduced tested on experimental data, improving the characterization of nonequilibrium dynamics many-body quantum systems.

Abstract The Möbius strip, a fascinating loop structure with one-sided topology, provides rich playground for manipulating the non-trivial topological behaviour of spinning particles, such as electrons, polaritons and photons, in both real parameter spaces. For photons resonating Möbius-strip cavity, occurrence an extra phase—known Berry phase—with purely origin is expected due to its evolution...
