论文摘要
我们正在启动FindBounce，这是一种用于评估欧几里得反弹动作的Mathematica软件包，该动作进入了量子和热场理论中亚稳态状态的衰减率。它基于多边形弹跳的概念，这是一种半分析方法，用于通过将电势离散为分段线性段来解决弹跳方程。这允许使用指定精度和任何数量的标量字段对任意电位进行快速，强大的评估。时间成本随着字段数量和/或段数量线性增长。具有20个字段的计算需要$ \ sim 2 $秒，$ 0.5 \％$ $ $ $。 FindBounce函数易于与本机Mathematica外观和感觉一起使用，它易于安装，并带有详细的文档和实例示例，例如成核温度的计算。我们还提供了与现有工具（如果适用）进行比较的定时基准。
We are launching FindBounce, a Mathematica package for the evaluation of the Euclidean bounce action that enters the decay rate of metastable states in quantum and thermal field theories. It is based on the idea of polygonal bounces, which is a semi-analytical approach to solving the bounce equation by discretizing the potential into piecewise linear segments. This allows for a fast and robust evaluation of arbitrary potentials with specified precision and any number of scalar fields. Time cost grows linearly with the number of fields and/or the number of segments. Computation with 20 fields takes $\sim 2$ seconds with $0.5\%$ accuracy of the action. The FindBounce function is simple to use with the native Mathematica look and feel, it is easy to install, and comes with detailed documentation and physical examples, such as the calculation of the nucleation temperature. We also provide timing benchmarks with comparisons to existing tools, where applicable.
