论文摘要
理想情况下，基于使用隧道电位在田间空间中的简单变分制的真空衰减的新方法非常适合研究重力对这种衰变的影响。该方法允许以新的和简单的方式证明许多结果，除其他结果外，重力校正倾向于使Minkowski或Anti de Sitter False False Vacua更稳定，或者更高的屏障会增加真空寿命。该方法还提供了非常干净的真空衰减引力淬火及其对电势特征的参数依赖性的图像，并允许在关键情况下研究真空吸尘器之间的BPS域壁。特别注意的是超对称电位，并讨论了近临界真空衰变，为此，它显示了如何在薄壁近似之外有效地应用新方法。
A new approach to vacuum decay in quantum field theory, based on a simple variational formulation in field space using a tunneling potential, is ideally suited to study the effects of gravity on such decays. The method allows to prove in new and simple ways many results, among others, that gravitational corrections tend to make Minkowski or Anti de Sitter false vacua more stable semiclassically or that higher barriers increase vacuum lifetime. The approach also offers a very clean picture of gravitational quenching of vacuum decay and its parametric dependence on the features of a potential and allows to study the BPS domain-walls between vacua in critical cases. Special attention is devoted to supersymmetric potentials and to the discussion of near-critical vacuum decays, for which it is shown how the new method can be usefully applied beyond the thin-wall approximation.
