弹跳解的简单梯度流方程

受 Chigusa、Moroi 和 Shoji 最近工作的启发，我们提出了一个新的简单梯度流方程来导出有助于假真空衰减的弹跳解。我们的讨论利用了科尔曼、格拉泽和马丁的讨论，我们在固定势能的同时解决了动能的最小化问题。弹跳解是作为该问题解的尺度变换而导出的。我们还表明，我们的方法的收敛对于初始配置的选择是稳健的。
Motivated by the recent work of Chigusa, Moroi, and Shoji, we propose a new simple gradient flow equation to derive the bounce solution which contributes to the decay of the false vacuum. Our discussion utilizes the discussion of Coleman, Glaser, and Martin, and we solve a minimization problem of the kinetic energy while fixing the potential energy. The bounce solution is derived as a scale transformation of the solution of this problem. We also show that the convergence of our method is robust against a choice of the initial configuration.
