The authors discuss a thermal router, based on magnetically excited solitons in a temperature-biased long Josephson junction. Their theoretical exploration of the coherent thermal transport in such a junction reveals the enhancement of both heat current and temperature, as induced by solitons (solitary waves, here ``fluxons'', each bearing a quantum of magnetic flux). Finally, they describe a multiterminal device that allows the distribution of heat among several reservoirs at will, the desired terminal being selected by shifting a soliton along the junction via the bias current. This could provide a platform for alternative logic processing based on heat, or on fluxons.
