• Abstract: Toroidal classification and geometric duality in quantum spin systems is presented. Through our classification and duality, we reveal that various bipartite quantum features in magnon-systems can manifest equivalently in both bipartite ferromagnetic and antiferromagnetic materials, based upon the availability of relevant Hamiltonian parameters. Additionally, the results highlight the antiferromagnetic regime as an ultra-fast dual counterpart to the ferromagnetic regime, both exhibiting identical capabilities for quantum spintronics and technological applications. Concrete illustrations are provided, demonstrating how splitting and squeezing types of two-mode magnon quantum correlations can be realized across ferro- and antiferromagnetic regimes.

  Bond-directional spin-spin interactions in a Fermi-Hubbard bilayer can be realized with ultracold fermions in Raman optical lattices. We analyze the Fermi-liquid and Mott-insulating phases, highlighting a correspondence between Dirac and Majorana quasi-particles. Our results establish that cold-atom quantum simulators based on Raman optical lattices can be a playground for extended Kitaev models.

  We propose a scheme for the generation of nonreciprocal multipartite entanglement in a two-mode cavity magnomechanical system. Our results show that the magnon self-Kerr effect can significantly enhance bipartite entanglement, which turns out to be non-reciprocal when the magetic field is tuned along the crystallographic axis.
