标题： Holographic phase transitions via thermally-assisted tunneling

摘要： 我们在全息模型中构建了热弹道解，该解描述了强耦合规范理论中去禁闭相和禁闭相之间的一阶相变。这个新的周期性欧几里得解通过热辅助隧穿过程表示相变，并在零温度下的$O(4)$对称真空泡和高温下的$O(3)$对称临界泡之间进行插值。精确的热弹道解可用于获得低温下的弹道作用量，从而更准确地确定真空衰变率，显著提高了全息模型中的先前估计。特别是，如果相变足够过冷，就可以得到临界温度从TeV尺度到$10^{12}$GeV范围内的引力波信号强度的新预测，其中一些预测有望被未来的引力波探测器探测到。 显示英文摘要

摘要： We construct the thermal bounce solution in holographic models that describes first-order phase transitions between the deconfined and confined phases in strongly-coupled gauge theories. This new, periodic Euclidean solution represents transitions that occur via thermally-assisted tunneling and interpolates between the $O(4)$-symmetric vacuum bubble at zero temperature and the high temperature $O(3)$-symmetric critical bubble associated with classical thermal fluctuations. The exact thermal bounce solution can be used to obtain the bounce action at low temperatures which allows for a more accurate determination of vacuum decay rates, significantly improving previous estimates in holographic models. In particular, provided the phase transition is sufficiently supercooled, new predictions are obtained for the gravitational wave signal strength for critical temperatures ranging from the TeV scale up to $10^{12}$ GeV, some of which are within reach of future gravitational wave detectors.
