Query: Inelastic thermoelectric transport and fluctuations in mesoscopic system   In the past decade, a new research frontier emerges at the interface between
physics and renewable energy, termed as the inelastic thermoelectric effects
where inelastic transport processes play a key role. The study of inelastic
thermoelectric effects broadens our understanding of thermoelectric phenomena
and provides new routes towards high-performance thermoelectric energy
conversion. Here, we review the main progress in this field, with a particular
focus on inelastic thermoelectric effects induced by the electron-phonon and
electron-photon interactions. We introduce the motivations, the basic pictures,
and prototype models, as well as the unconventional effects induced by
inelastic thermoelectric transport. These unconventional effects include the
separation of heat and charge transport, the cooling by heating effect, the
linear thermal transistor effect, nonlinear enhancement of performance, Maxwell
demons, and cooperative effects. We find that elastic and inelastic
thermoelectric effects are described by significantly different microscopic
mechanisms and belong to distinct linear thermodynamic classes. We also pay
special attention to the unique aspect of fluctuations in small mesoscopic
thermoelectric systems. Finally, we discuss the challenges and future
opportunities in the field of inelastic thermoelectrics.
