匀加速探测器对真空中无质量Rarita-Schwinger场的响应

Response of a uniformly accelerated detector to massless Rarita-Schwinger fields in vacuum

Qinglin Li, Hongwei Yu, Wenting Zhou

摘要:

本文研究了由二能级原子与真空无质量拉里塔-施温格场非线性耦合构成的匀加速探测器的响应。我们首先推广Dalibard,Dupont-Roc和Cohen-Tannoudji在线性耦合情况下开发的形式主义,然后我们计算加速原子的原子能量的平均变化率。结果表明,处于基态的匀加速原子与真空Rarita-Schwinger场涨落相互作用时会自发地跃迁到激发态,与标量场、电磁场和Dirac场耦合时不同的是,原子的激发速率中出现了与加速度的六次方和八次方成正比的项.

英文摘要:

We study the response of a uniformly accelerated detector modeled by a two-level atom nonlinearly coupled to vacuum massless Rarita-Schwinger fields. We first generalize the formalism developed by Dalibard, Dupont-Roc, and Cohen-Tannoudji in the linear coupling case, and we then calculate the mean rate of change of the atomic energy of the accelerated atom. Our result shows that a uniformly accelerated atom in its ground state interacting with vacuum Rarita-Schwinger field fluctuations would spontaneously transition to an excited state and the unique feature in contrast to the case of the atom coupled to the scalar, electromagnetic and Dirac fields is the appearance of terms in the excitation rate which are proportional to the sixth and eighth powers of acceleration.
