    "abstract": "We study numerically the damping of quantum oscillations and the increase of\nentropy with time in model spin systems decohered by a spin bath. In some\nexperimentally relevant cases, the oscillations of considerable amplitude can\npersist long after the entropy has saturated near its maximum, i.e. when the\nsystem has been decohered almost completely. Therefore, the pointer states of\nthe system demonstrate non-trivial dynamics. The oscillations exhibit slow\npower-law decay, rather than exponential or Gaussian, and may be observable in\nexperiments.",
