false vacuum

既定 英語（イギリス） (en-GB)

名詞

(physics, quantum field theory) A (hypothetical) metastable vacuum whose energy state is at a local minimum different from the global minimum; a vacuum that is relatively stable and long-lived but which still may decay to a lower-energy state.

日本語の意味

（物理学、量子場理論において）仮説上の準安定な真空状態。エネルギー状態が全体の最低値ではなく局所的な最低値にあるため、比較的安定で長寿命であるが、より低いエネルギー状態に崩壊する可能性がある状態。

このボタンはなに？

Some cosmologists worry that the universe currently sits in a false vacuum that could decay into a true vacuum and release enormous energy.

一部の宇宙論学者は、宇宙が現在偽真空にあり、それが真の真空へ崩壊して莫大なエネルギーを放出する可能性を懸念している。

(physics, quantum field theory) A (hypothetical) metastable vacuum whose energy state is at a local minimum different from the global minimum; a vacuum that is relatively stable and long-lived but which still may decay to a lower-energy state.

The energy density of the false vacuum can be attributed entirely to the Higgs fields. Furthermore, as can be seen in figure 3.5, any deviation of the Higgs fields from their false-vacuum values would require an increase in energy density. This implies that the false vacuum has a peculiar property which distinguishes it from all familiar materials: when the volume of a region of false vacuum is increased, the energy density cannot decrease, but instead remains at a constant value.
