一种新的空泡成核机制:经典相变

A New Mechanism for Bubble Nucleation: Classical Transitions

Richard Easther, John T. Giblin, Lam Hui, Eugene A. Lim

摘要:

给定一个具有亚稳态极小值的标量场,气泡以量子力学的方式成核。当气泡碰撞时,储存在气泡壁中的能量转换成场的动能。这种动能可以促进新气泡的经典成核,其处于低于“母”气泡的最小值。这个过程是有效的和经典的,并改变了泡沫形成的动力学和统计模型与多个真空,相对于来自量子隧穿。

英文摘要:

Given a scalar field with metastable minima, bubbles nucleate quantum mechanically. When bubbles collide, energy stored in the bubble walls is converted into kinetic energy of the field. This kinetic energy can facilitate the classical nucleation of new bubbles in minima that lie below those of the "parent" bubbles. This process is efficient and classical, and changes the dynamics and statistics of bubble formation in models with multiple vacua, relative to that derived from quantum tunneling.
