Topological and kinetic origins of fractional thermal conductance at the topological insulator--superconductor interface
This paper establishes a theorem proving that thermal conductance alone cannot distinguish between topological and kinetic origins of fractional thermal transport at topological insulator–superconductor interfaces, demonstrating that the observed half-integer plateau in recent experiments arises from full equilibration of co-propagating modes rather than non-Abelian topology, and proposing that charge-sector measurements like anomalous Lorenz ratios and shot noise are required to resolve this ambiguity.
