Controlling heat and particle currents in nanodevices by quantum observation

THERMOELECTRICS: Observe and control The presence of a quantum observer, acting locally in a thermoelectric nanodevice, is shown to be enough to change its heat and electronic transport path. In quantum mechanics the observation of a phenomenon can affect its outcome. Local quantum observation of a...
