Universal scaling of higher-order cumulants in quantum isotropic spin chains
In the isotropic Heisenberg spin chain, higher-order cumulants of spin transfer scale with exponents identical across orders for spin-helix states (nu about 0.45) but differ for domain-wall states (nu3=nu4 about 2*nu1 about 1.3).
