亚稳态的量子衰变（“假真空”）被认为是新宇宙的气泡成核和早期宇宙相变的机制。实验表明，在高度各向异性的凝聚态系统中，通过量子隧穿成核的孤子畴壁所包围的区域内，会发生假真空衰变。这种现象提供了一个令人信服的例子，假真空衰变在实验室中。
Quantum decay of metastable states (‘false vacua’) has been proposed as a mechanism for bubble nucleation of new universes and phase transitions in the early universe. Experiments indicate the occurrence of false vacuum decay, within a region bounded by soliton domain walls that nucleate via quantum tunneling, in a highly anisotropic condensed matter system. This phenomenon provides a compelling example of false vacuum decay in the laboratory.
