阿哈罗诺夫-玻姆辐射

Aharonov-Bohm Radiation

Katherine Jones-Smith, Harsh Mathur, Tanmay Vachaspati

摘要:

在真空中振荡的螺线管由于Aharonov-Bohm(AB)相互作用而成对产生带电粒子。计算了带电标量粒子的辐射方向图和辐射功率。我们扩展的螺线管分析宇宙弦,并发现从尖点和扭结环增强辐射。我们认为,通过类比的电磁AB相互作用,宇宙弦应该发射光子,由于引力AB相互作用的领域在圆锥时空的宇宙弦。我们计算的发射从一个扭结,并发现它是类似的顺序,从一个尖点发射,但扭结是远远多于尖点,并可能提供一个更有趣的观测签名。

英文摘要:

A solenoid oscillating in vacuum will pair produce charged particles due to the Aharonov-Bohm (AB) interaction. We calculate the radiation pattern and power emitted for charged scalar particles. We extend the solenoid analysis to cosmic strings, and find enhanced radiation from cusps and kinks on loops. We argue by analogy with the electromagnetic AB interaction that cosmic strings should emit photons due to the gravitational AB interaction of fields in the conical spacetime of a cosmic string. We calculate the emission from a kink and find that it is of similar order as emission from a cusp, but kinks are vastly more numerous than cusps and may provide a more interesting observational signature.
