受驱动单粒子量子回旋加速器

Driven One-Particle Quantum Cyclotron

Xing Fan, Gerald Gabrielse

摘要:

量子回旋加速器是一个被捕获的电子或正电子,只占据其最低的回旋加速器和自旋状态。求解了在热平衡条件下,与探测振荡器耦合的受驱动量子回旋加速器的主方程,这是该耦合开放系统的首次量子计算。作为驱动频率的函数的回旋加速器和自旋量子跳跃的预测速率,对于检测运动和其热储层之间的小耦合,与已经预测和用于过去测量的速率有很大不同。计算表明,更精确的电子磁矩测量是可能的,因为需要调查粒子物理学标准模型的最精确预测与基本粒子属性的最精确测量之间的当前差异。

英文摘要:

A quantum cyclotron is one trapped electron or positron that occupies only its lowest cyclotron and spin states. A master equation is solved for a driven quantum cyclotron with a QND (quantum nondemolition) coupling to a detection oscillator in thermal equilibrium - the first quantum calculation for this coupled and open system. The predicted rate of cyclotron and spin quantum jumps as a function of drive frequency, for a small coupling between the detection motion and its thermal reservoir, differs sharply from what has been predicted and used for past measurements. The calculation suggests a ten times more precise electron magnetic moment measurement is possible, as needed to investigate current differences between the most precise prediction of the standard model of particle physics, and the most accurate measurement of a property of an elementary particle.
