A tunable noise rectifier is construed in which the net output current results from the interplay of equilibrium thermal noise and a pulsated amplitude modulation propagating along a periodic potential (thermal conveyer). The transport efficiency of such a device attains its maximum for an optimal value of the temperature and the pulse speed. A thermal conveyer whose modulation parameters depend on the output current, may operate as an active noise rectifier for an appropriate setting of the control parameters.

Abstract
A tunable noise rectifier is construed in which the net output current results from the interplay of equilibrium thermal noise and a pulsated amplitude modulation propagating along a periodic potential (thermal conveyer). The transport efficiency of such a device attains its maximum for an optimal value of the temperature and the pulse speed. A thermal conveyer whose modulation parameters depend on the output current, may operate as an active noise rectifier for an appropriate setting of the control parameters.File in questo prodotto:
