Degenerate perturbation theory on a multiorbital Hubbard model shows isotropic superexchange arises mainly from ground-state Kramers doublet hopping while anisotropy comes from excited multiplets, yielding an orbital design rule for quasi-isotropic exchange in rare-earth insulators.

Topological Hall effect observed in antiferromagnetic Co-doped Fe3GaTe2, attributed to field-induced chiral spin textures possibly including AFM skyrmions that transition to FM skyrmions.
Skyrmions driven by biaxial AC currents in a magnetic film form Lissajous trajectories in the plane, deviating from ideal paths as temperature increases via changes in Hall angle and thermal fluctuations.
Persistent homology analysis of Baijiu reveals a three-stage maturation pathway converging to a universal topological attractor that defines optimal aging independent of chronological time.

Emergence of Lissajous trajectories in skyrmion oscillator
Skyrmions driven by biaxial AC currents in a magnetic film form Lissajous trajectories in the plane, deviating from ideal paths as temperature increases via changes in Hall angle and thermal fluctuations.
