论文摘要
我们使用截短的保形空间方法研究了缩放液和三个智慧领域理论中错误真空的衰变，并将数值结果与薄壁限制中的理论预测进行了比较。在Ising情况下，结果与先前关于量子自旋链和$φ^4 $量子场理论的研究一致。特别是我们确认，虽然理论预测获得了气泡成核速率对潜热权利的依赖性，但它们却被依赖模型的整体系数关闭。另一方面，三个智能模型使我们能够检查更多的外来真空退化结构，例如三个真空或两个不对称的真空吸尘器，这使我们通过使用不同的扰动来提高真空脱脂性来研究几种虚假真空衰变的新型情况。
We study the decay of the false vacuum in the scaling Ising and tricritical Ising field theories using the Truncated Conformal Space Approach and compare the numerical results to theoretical predictions in the thin wall limit. In the Ising case, the results are consistent with previous studies on the quantum spin chain and the $φ^4$ quantum field theory; in particular we confirm that while the theoretical predictions get the dependence of the bubble nucleation rate on the latent heat right, they are off by a model dependent overall coefficient. The tricritical Ising model allows us on the other hand to examine more exotic vacuum degeneracy structures, such as three vacua or two asymmetric vacua, which leads us to study several novel scenarios of false vacuum decay by lifting the vacuum degeneracy using different perturbations.
