    "abstract": "We analyze the Zeno phenomenon in quantum field theory. The decay of an\nunstable system can be modified by changing the time interval between\nsuccessive measurements (or by varying the coupling to an external system that\nplays the role of measuring apparatus). We speak of quantum Zeno effect if the\ndecay is slowed and of inverse quantum Zeno (or Heraclitus) effect if it is\naccelerated. The analysis of the transition between these two regimes requires\nclose scrutiny of the features of the interaction Hamiltonian. We look in\ndetail at quantum field theoretical models of the Lee type.",
