Transport in dimerized and frustrated spin systems
We analyze the Drude weight for both spin and thermal transport of one-dimensional spin-12 systems by means of exact diagonalization at finite temperatures. While the Drude weights are non-zero for finite systems, we find indications of a vanishing of the Drude weights in the thermodynamic limit for...
