论文摘要
本文描述了在存在标量第五力的情况下电磁场中电荷粒子的动力学。专注于Chameleon场将诱导的第五力，其轮廓可以在实验室中正确设计，它对静态和均匀磁场中粒子的回旋体运动进行了物理影响。第五力诱导了轨迹的漂移，该轨迹在分析上进行了估计，并将其与两个嵌套圆柱体内变色龙场的数值计算进行了比较。讨论了这种漂移的效果和可检测性的大小，以指出这可能提供了一种新的实验设计，以测试实验室中的小第五力。更重要的是，在宏观水平上，它诱导了可以原则上测量的电流，甚至可以允许一个人访问腔体内标量场的横向轮廓。在这两种情况下，将磁场与局部重力场对准都抑制了牛顿重力的影响，牛顿重力的效果将比第五力的几个阶大，否则却比第五力的重力大，并且粒子上腔的牛顿重力也被认为可以忽略不计。鉴于这种见解，这种实验设置具有两种影响 - 在单个粒子和宏观水平上 - 可能需要注意以证明其在实验室中的实际可行性。
This article describes the dynamics of a charge particle in a electromagnetic field in presence of a scalar fifth force. Focusing to the fifth force that would be induced by a chameleon field, the profile of which can be designed properly in the laboratory, it draws its physical effects on the cyclotron motion of a particle in a static and uniform magnetic field. The fifth force induces a drift of the trajectory that is estimated analytically and compared to numerical computations for profiles motivated by the ones of a chameleon field within two nested cylinders. The magnitude of the effect and the detectability of this drift are discussed to argue that this may offer a new experimental design to test small fifth force in the laboratory. More important, at the macroscopic level it induces a current that can in principle also be measured, and would even allow one to access the transverse profile of the scalar field within the cavity. In both cases, aligning the magnetic field with the local gravity field suppresses the effects of Newtonian gravity that would be several order larger than the ones of the fifth force otherwise and the Newtonian gravity of the cavity on the particle is also argued to be negligible. Given this insight, this experimental set-up, with its two effects -- on a single particle and at the macroscopic level -- may require attention to demonstrate its actual feasability in the laboratory.
