Josephson tunnel junctions are proposed as efficient phase-tunable thermal rectifiers. The latter exploit the strong temperature dependence of the superconducting density of states and phase-dependence of heat currents flowing through Josephson junctions to operate. Remarkably, large heat rectification coefficients up to similar to 800% can potentially be achieved using conventional materials and standard fabrication methods. In addition, these devices allow for the in situ fine tuning of the thermal rectification magnitude and direction.
