    "abstract": "A quantum many-body model is presented with features similar to those of\ncertain particle detectors. The energy spectrum contains a single metastable\n\u0027ready\u0027-state and macroscopically-distinct \u0027pointer\u0027 states. Measurements do\nnot pose paradoxes or require interventions outside the field theory formalism.\nTransitions into classical-like states can be triggered by a single particle\nwith help of the thermal bath. Schroedinger cat states are associated with\nsuperpositions of inequivalent vacua, thus relating wavefunction collapse to\nthe dynamics of symmetry breaking in phase transformations.",
