    "abstract": "We study a general macroscopic quantum system of a finite size, which will\nexhibit a symmetry breaking if the system size goes to infinity, when the\nsystem interacts with an environment. We evaluate the decoherence rates of the\nanomalously fluctuating vacuum (AFV), which is the symmetric ground state, and\nthe pure phase vacua (PPVs). By making full use of the locality and huge\ndegrees of freedom, we show that there can exist an interaction with an\nenvironment which makes the decoherence rate of the AFV anomalously fast,\nwhereas PPVs are less fragile.",
