Query: Brownian thermal transistors and refrigerators in mesoscopic systems   Fluctuations are significant in mesoscopic systems and of particular
importance in understanding quantum transport. Here, we show that fluctuations
can be considered as a resource for the operations of open quantum systems as
functional devices. We derive the statistics of the thermal transistor
amplification factor and the cooling-by-heating refrigerator efficiency under
the Gaussian fluctuation framework. Statistical properties of the stochastic
thermal transistor and the cooling-by-heating efficiency are revealed in the
linear-response regime. We clarify the unique role of inelastic processes on
thermal transport in mesoscopic systems. We further show that elastic and
inelastic processes lead to different bounds based on the linear transport
coefficients by establishing a generic theoretical framework for mesoscopic
heat transport, which treats electron and bosonic collective excitations in an
equal-footing manner. The underlying physics are illustrated concretely using a
double-quantum-dot three-terminal system, though the theory applies to more
general systems.
