In this talk, I will present a quantum absorption refrigeration scheme consisting of electronic nanocavities in solid state coupled via resonant tunneling quantum dots. Absorption refrigerators (somewhat counter-intuitively) harvest energy from a hotter dissipative source to produce the cooling effect, unlike conventional refrigerators which are driven by external work sources. The device we propose harvests energy from hotspots in circuits to selectively cool down regions of interest within the circuit. We will discuss a complete thermodynamic characterization of the device as well as its optimal and stopping configurations. The talk will be concluded by discussing an on demand thermal control scheme for a chain of electronic nanocavities, which paves way towards the efficient management of dissipated heat in quantum circuits.
