真空泡壁的韧致辐射

Bremsstrahlung Radiation At a Vacuum Bubble Wall

Jae-Weon Lee, Kyungsub Kim, Chul H. Lee, Ji-ho Jang

摘要:

当带电粒子与真空气泡碰撞时,由于快速减速,它们可以辐射出强烈的电磁波。由于粒子通过这种韧致辐射的能量损失,即使在保持热平衡时,也存在作用在气泡壁上的不可忽略的阻尼压力。在非相对论区域,这个压力与壁面的速度成正比,可能影响早期宇宙中的气泡动力学。

英文摘要:

When charged particles collide with a vacuum bubble, they can radiate strong electromagnetic waves due to rapid deceleration. Owing to the energy loss of the particles by this bremsstrahlung radiation, there is a non-negligible damping pressure acting on the bubble wall even when thermal equilibrium is maintained. In the non-relativistic region, this pressure is proportional to the velocity of the wall and could have influenced the bubble dynamics in the early universe.
