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.

Numerical evidence from exact diagonalization supports a foliated non-Abelian Fibonacci phase in 9-layer systems alongside stability of decoupled Laughlin states under interlayer pseudopotential interactions.
A photonic cavity creates a chirality-controlled rotating pinning potential that performs branch-conditioned braiding of non-Abelian anyons and maps the result onto measurable cavity coherence.
A hardware-native error model and loss-disciplined protocol for DI-QKD on Majorana processors is proposed with an EAT security proof, but secure distances are strictly bounded by poisoning-induced visibility collapse during photonic round-trips.
A hetero-dimensional superconducting metamaterial with magnetic adatoms hosts a tunable weak-to-bulk-dissociated topological superconducting phase without requiring spin-orbit coupling.
Multiple-braiding sequences with multiplicities up to nine in SU(2)_k anyon models enable approximation of a universal gate set {H, T, CNOT} for k>2, k≠4, with numerical evidence from genetic algorithms.
In a 2D model Hamiltonian, orbital Hall conductivity quantizes when altermagnetism exceeds sp-hybridization while spin Hall quantizes when Rashba SOC is weaker, with both independent of the other coupling and arising from Fermi-surface Berry curvature.
Edge reconstruction of a ν=1 quantum Hall edge into a ν=1/3 side strip doubles topological sectors to Z2×Z2 degeneracy, producing 4π Josephson periodicity with energetically decoupled Z2 states.
A synthesis of van der Waals Josephson junction research showing how 2D material diversity and symmetry control open routes to novel quantum devices and sensors.
Analytical calculation for N≤7 shows composite fermion wavefunction yields lower two-quasiparticle excitation energy per particle than Laughlin, with the difference decreasing as system size increases.
