SimpleBounce : a simple package for the false vacuum decay

Ryosuke Sato

AI总结:

SimpleBounce是一个C++软件包,基于流动方程和尺度变换高效求解假真空衰变的反弹解,支持1-8个标量场,精度高且速度快。

摘要:

我们介绍SimpleBounce,一个用于寻找假真空衰变反弹解的C++软件包。该软件包基于作者提出的流动方程,解决了Coleman-Glaser-Martin的约化问题:在固定势能的同时最小化动能的最小化问题。反弹构型通过该问题解的尺度变换获得。对于具有1-8个标量场的模型,反弹作用可以在O(0.1)秒内以O(0.1)%的精度计算。该软件包可在https://github.com/rsato64/SimpleBounce获取。

英文摘要:

We present SimpleBounce, a C++ package for finding the bounce solution for the false vacuum decay. This package is based on a flow equation which is proposed by the author and solves Coleman-Glaser-Martin's reduced problem: the minimization problem of the kinetic energy while fixing the potential energy. The bounce configuration is obtained by a scale transformation of the solution of this problem. For models with 1--8 scalar field(s), the bounce action can be calculated with O(0.1) % accuracy in O(0.1) s. This package is available at https://github.com/rsato64/SimpleBounce.
