强均匀磁场中非对易平面的后向康普顿散射和QED

Backward Compton Scattering and QED with Noncommutative Plane in the Strong Uniform Magnetic Field

Wei Huang, Wang Xu, Mu-Lin Yan

摘要:

研究了在强均匀磁场中,由最低朗道能级(LLL)效应引起的非对易面(NCP),以及具有NCP的QED(QED-NCP)。类似于量子霍尔效应的凝聚态理论,引入了有效填充因子$f(B)$来表征电子停留在LLL上的可能性。计算了初始光子非偏振和偏振时加速器中后向康普顿散射微分截面的解析和数值结果。本文对BL 38 B2的现有资料进行了粗略的分析,并与数值预报作了比较。我们提出了一种精确测量强垂直磁场中后向康普顿散射微分截面的方法,这将有助于揭示QED-NCP效应。

英文摘要:

In the strong uniform magnetic field, the noncommutative plane (NCP) caused by the lowest Landau level (LLL) effect, and QED with NCP (QED-NCP) are studied. Being similar to the condensed matter theory of quantum Hall effect, an effective filling factor $f(B)$ is introduced to character the possibility that the electrons stay on the LLL. The analytic and numerical results of the differential cross section for the process of backward Compton scattering in the accelerator with unpolarized or polarized initial photons are calculated. The existing data of BL38B2 in Spring-8 have been analyzed roughly and compared with the numerical predictions primitively. We propose a precise measurement of the differential cross sections of backward Compton scattering in a strong perpendicular magnetic field, which may lead to reveal the effects of QED-NCP.
