In recent years, the study of heat to work conversion has been re-invigorated by
nanotechnology. Steady-state devices do this conversion without any macroscopic moving …

Engines are systems and devices that convert one form of energy into another, typically into
a more useful form that can perform work. In the classical setup, physical, chemical, and …

We review recent theoretical work on thermoelectric energy harvesting in multi-terminal
quantum-dot setups. We first discuss several examples of nanoscale heat engines based on …

Rectification of thermal fluctuations in mesoscopic conductors is the key idea behind recent
attempts to build nanoscale thermoelectric energy harvesters to convert heat into useful …

We describe nonlinear phonon-thermoelectric devices where charge current and electronic
and phononic heat currents are coupled, driven by voltage and temperature biases, when …

We demonstrate experimentally an autonomous nanoscale energy harvester that utilizes the
physics of resonant tunneling quantum dots. Gate-defined quantum dots on GaAs/AlGaAs …

We investigate a heat to charge current converter consisting of a single-level quantum dot
coupled to two ferromagnetic metals and one ferromagnetic insulator held at different …

The thermodynamic uncertainty relation, quantifying a trade-off among average current, the
associated fluctuation (precision), and entropy production (cost), has been formulated at …

We propose and analyze a simple mesoscopic quantum heat engine that exhibits both high
power and high efficiency. The system consists of a biased Josephson junction coupled to …

We study the statistical properties of charge and energy transport in electron conducting
junctions with electron-phonon interactions, specifically, the thermoelectric efficiency and its …
