标题： A New Mechanism for Bubble Nucleation: Classical Transitions

摘要： 给定一个具有亚稳态极小值的标量场时，气泡会通过量子机制形成。当气泡发生碰撞时，气泡壁中储存的能量会转化为场的动能。这种动能可以促进在较“母”气泡极小值更低的极小值处经典地形成新的气泡。这个过程是高效且经典的，在具有多个真空的模型中，与从量子隧穿得出的结果相比，它改变了气泡形成的动力学和统计特性。 显示英文摘要

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.
