I’ll present recent exact results on the finite temperature and magnetic field transport in the one dimensional spin-1/2 Heisenberg model obtained by the Bethe ansatz (BA) method. Furthermore, I’ll discuss the thermodynamics, thermal transport and ESR of the spin S=1 easy-plane quasi-one dimensional quantum magnet NiCl2-4SC(NH2)2 (DTN) as well as induced magnetisation by light.
