    "abstract": "We use a spin-1/2 model to analyze tunnelling in a double well system coupled\nto an external reservoir. We consider different noise sources such as\nfluctuations on the height and central position of the barrier and propose an\nexperiment to observe these effects in trapped ions or atoms.",
