✦ Synopsis

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.

The thermal conductivities and spin polarization induced by the temperature gradient are investigated in a Rashba spin-orbit-coupled two-dimensional electron gas. In this spin-orbit-coupled system in the presence of nonmagnetic or magnetic electron-impurity scattering, the Wiedemann-Franz law still
