Enhancement of the Thermal Conductivity in gapped Quantum Spin Chains
Keiji Saito, Seiji Miyashita
Abstract
We study mechanism of magnetic energy transport, motivated by recent measurements of the thermal conductivity in low dimensional quantum magnets. We point out a possible mechanism of enhancement of the thermal conductivity in gapped magnetic system, where the magnetic energy transport plays a crucial role. This mechanism gives an interpretation for the recent experiment of CuGeO3, where the thermal conductivity depends on the crystal direction.
