Finite temperature and magnetic field transport in 1D quantum magnets
28.04.2015 at 14:15
I’ll present recent exact results on the finite temperature and magnetic field magnetothermal transport in the one dimensional spin-1/2 Heisenberg model obtained using the Bethe ansatz (BA) method, in particular, the behaviour of spin Drude weight as a function of magnetic field down to low temperatures. Furthermore, I’ll discuss the thermodynamics, thermal transport and dynamics of the spin S=1 easy-plane quasi-one dimensional quantum magnet NiCl2-4SC(NH2)2 (DTN).
