The understanding of coupled particles and heat transport in complex
systems is a fundamental problem, also of practical interest in connection
with the challenging task of developing high-performance thermoelectric
materials.

In view of meeting the energy challenge of the future, the possibility to
build thermal diodes or efficient thermoelectric devices for cooling or
power generation, may play an important increasing role. The understanding
of the underlying microscopic nonlinear mechanisms may prove to be relevant
for the solution of this important societal problem

Here we discuss how the combined effect of nonlinearity and symmetry
breaking can lead to important consequences such as the possibility to
control the heat current or wave propagation in nonlinear media. We will
then discuss thermoelectric transport phenomena from the perspective of
dynamical nonlinear systems, focusing on stylized classical and quantum
models, including the disordered hard-point gas.
