Theoretical and experimental work concerned with dynamic fluctuations has developed into
a very active and fascinating subfield of mesoscopic physics. We present a review of this …

The quantum of thermal conductance of ballistic (collisionless) one-dimensional channels is
a unique fundamental constant. Although the quantization of the electrical conductance of …

Quantum physics predicts that there is a fundamental maximum heat conductance across a
single transport channel and that this thermal conductance quantum, GQ, is universal …

Recent experimental work on locally gated graphene layers resulting in pn junctions has
revealed the quantum Hall effect in their transport behavior. We explain the observed …

In the previous chapter, we discussed the thermal conductance measurement of integer

We investigate the rectification of thermal fluctuations in a mesoscopic on-chip heat engine.
The engine consists of a hot chaotic cavity capacitively coupled to a cold cavity which …

We derive a stochastic path integral representation of counting statistics in semiclassical
systems. The formalism is introduced on the simple case of a single chaotic cavity with two …

Quantum mechanics and Coulomb interaction dictate the behaviour of small circuits. The
thermal implications cover fundamental topics from quantum control of heat to quantum …

The universal quantization of thermal conductance provides information on a state's
topological order. Recent measurements revealed that the observed value of thermal …

When assembling individual quantum components into a mesoscopic circuit, the interplay
between Coulomb interaction and charge granularity breaks down the classical laws of …
