https://en.wikipedia.org/wiki/Misalignment%20mechanism | The misalignment mechanism is a hypothesized effect in the Peccei–Quinn theory proposed solution to the strong-CP problem in quantum mechanics. The effect occurs when a particle's field has an initial value that is not at or near a potential minimum. This causes the particle's field to oscillate around the nearest mini... |
