Dynamic Thermal Management and Tunable Magnetic Phase Transitions via a Dynamic Chiral Thomson Effect on Rotating Conductors

In this work we will illustrate a new wavelike non linear heat conduction model aimed to implement chiral thermal management and dynamic tunable chiral thermal emission on rotating conductors exposed to chopped laser beam. We will assume the existence of a rotational thermal Hall effect due to a self-induced out of equilibrium Barnett magnetic field showing that they it allows to deviate transversally the harmonic heat flux and to modulate the phase velocity of helical thermal waves propagating on the rotating metallic disks. We deduce a new dynamic chiral Thomson effect proportional to the angular velocity vector of the disk, giving an estimate of its Thomson coefficient in the case of an iron sample. We show that the laser induced chiral Thomson electric field and the time dependent Barnett magnetic field can be exploited to enhance and dynamic control magnetic phase transitions. We introduce finally a dynamic tunable chiral thermal emissivity dependent on a gauge breaking thermal Poynting vector outlining its relevance for a novel rotational approach to non-reciprocal photonics.
