Popis: In this paper, we propose a device that picks up a periodic but weak signal by amplifying it assisted by the existing background noise. The device consists of a doped layered semiconductor with three gates that generate a one-dimensional double-well potential along the semiconductor. A laser coolant is to be shined on the other side of the central gate perpendicular to the one-dimensional layer causing triple-well potential. A weak tunable oscillator imposed parallel to the layer that rocks the potential landscape can pick up an incoming signal of interest as a result of resonance. To justify the model, we carried out analytic calculation as well as Monte Carlo simulation. The two approaches agree reasonably well for all the different parameter values we used.
