Description
In this paper we study thermal transport in the one-dimensional spin S=1 and the two dimensional spin S=1/2 Heisenberg antiferromagnets, using the modified spin wave theory and the Kubo linear response formalism, to calculate the thermal conductivity. The low-temperature thermal Drude weights, in both cases, are non-zero at finite temperature indicating a ballistic behavior.
