Query: Thermal conductivity of one-dimensional spin-1/2 systems   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.
