| Description |
I will review the past year results on the emergence of diffusive and super diffusive, KPZ like, spin transport in spin chains with non-abelian symmetry (like in the Heisenberg model) which has received a large experimental and theoretical attention. I will show how proving the emergence of KPZ fluctuations in an integrable spin chain is harder than usual and what the theory of generalised hydrodynamics can say about it. |
