Abstract

Quantum mechanics sets an upper bound on the amount of charge flow as well as on the amount of heat flow in ballistic one-dimensional channels. The two relevant upper bounds, that combine only fundamental constants, are the quantum of the electrical conductance, Ge=e^2/h, and the quantum of the thermal conductance, Gth=π^2k_B^2T/3h. Remarkably, the latter does not depend on particles charge; particles exchange statistics; and even the interaction strength among the particles.


 


However, unlike the relative ease in determining accurately the quantization of the electrical conductance, measuring accurately the thermal conductance is more challenging.
