Abstract

Heat transport through a column of superfluid 4 He has been observed experimentally to self-organize, resulting in a thermal gradient that exactly matches the gradient in the superfluid transition temperature across the column, leaving the entire sample at a constant distance from the superfluid critical point1. We describe a new experiment that is designed to accomplish three objectives: 1) search for the upper critical heat flux above which self-organized heat transport can no longer occur, 2) measure the heat capacity of the self-organized heat transport state, and 3) test recent theoretical predictions 2,3 of the microscopic mechanism that is responsible for this self-organization. PACS numbers: 64.60 Ht, 66.60 +a, 67.40 Pm.
