我们认为，经典跃迁可能是解释在超流氦3中观察到的快速A-B相变的长期困惑的关键，而标准理论认为它是不可观察到的缓慢。结果表明，在测量的时间尺度上，畴壁之间的碰撞能够达到通过均匀成核无法达到的相。我们证明了与先前观察的定性一致，并提供了一个明确的、独特的预测，可以通过未来的实验或对现有数据的具体分析来验证。
We argue that classical transitions can be the key to explaining the long standing puzzle of the fast A-B phase transition observed in superfluid Helium 3 while standard theory expects it to be unobservably slow. Collisions between domain walls are shown to be capable of reaching phases inaccessible through homogenous nucleation on the measured timescales. We demonstrate qualitative agreements with prior observations and provide a definite, distinctive prediction that could be verified through future experiments or, perhaps, a specific analysis of existing data.
