It was recently predicted that phonon (or heat) transport through quasi-one-dimensional structures should exhibit a universal conductance quantum in the ballistic regime. Analogously to the quantum of electrical conductance (s ΒΌ e 2 =h), the quantum of thermal conductance is independent of material
The low-frequency resistance noise of quantum point contacts is shown to be dominated by fluctuations in the electrostatic potential. Both in the ballistic and in the quantum Hall regime, the noise is strongly suppressed if the conductance is quantized. The suppression is enhanced by a strong magnet
