School PHYSICS Abstract: Many-body systems are very good sensors when tuned close to their critical points. In particular, these systems may undergo a phase transition by a tiny change of the order parameter, making it extremely sensitive to the parameter. Their usefulness in metrology has been quantified by showing that their Fisher information scales super-linearly in the vicinity of the critical point. The Fisher information is, however, a relevant figure of merit in local parameter estimation, i.e., when the parameter is readily known with a good precision. More realistically, one has a limited knowledge about the parameter, often given by a prior distr ... |
