We investigate heat rectification in a two-qubit system coupled via the Dzyaloshinskii-Moriya (DM) interaction. We derive analytical expressions for heat currents and thermal rectification and provide possible physical mechanisms behind the observed results. We show that the anisotropy of DM interaction in itself is not sufficient for heat rectification to occur, and some other form of asymmetry is needed. We employ off-resonant qubits as the source of this asymmetry. We find the regime of… Expand
