Abstract

We demonstrate that a three-terminal harmonic symmetric chain in the presence of a Coriolis force, produced by a rotating platform which is used to place the chain, can produce thermal rectification. The direction of heat flow is reconfigurable and controlled by the angular velocity $\Omega$ of the rotating platform. A simple three terminal triangular lattice is used to demonstrate the proposed principle.
