Thermal conductivity of one-dimensional spin-1/2 systems
arXiv:cond-mat/0406378 · doi:10.1016/j.physb.2005.01.432
Abstract
We analyze the thermal conductivity of frustrated spin-1/2 chains within linear-response theory focusing on its frequency dependence at finite temperatures. Using exact diagonalization, the low-frequency limit of the thermal conductivity is discussed in the high-temperature regime.
