A magneto-gravitational trap for precision studies of gravitational quantum states
摘要：
观测时间是提高悬浮在反射面上粒子引力量子态测量精度的关键参数。我们提出了一种新的方法，在这种状态下的原子，反原子，中子和其他具有磁矩的粒子的长期限制。地球引力场和反射镜将粒子限制在垂直方向。源自通过垂直导线的电流的磁场将颗粒限制在径向上。在适当的条件下，沿这两个方向的运动在很大程度上是解耦的。我们估计的问题的特征参数，并列出可能的系统影响，限制存储时间，由于耦合的两个运动。在低粒子速度和磁场的限制下，精确控制粒子的运动和在阱中的长时间储存，可以为引力、光学和超精细光谱学提供理想的条件：灵敏地验证反氢原子的等效原理，提高原子和反原子的光学和超精细光谱学的精度，提高原子和反原子光谱学的精度，提高原子和反原子光谱学的精度。用于改进中子、原子和反原子实验中额外基本相互作用的约束。
英文摘要：
Observation time is the key parameter for improving the precision of measurements of gravitational quantum states of particles levitating above a reflecting surface. We propose a new method of long confinement in such states of atoms, anti-atoms, neutrons and other particles possessing a magnetic moment. The Earth gravitational field and a reflecting mirror confine particles in the vertical direction. The magnetic field originating from electric current passing through a vertical wire confines particles in the radial direction. Under appropriate conditions, motions along these two directions are decoupled to a high degree. We estimate characteristic parameters of the problem, and list possible systematic effects that limit storage times due to the coupling of the two motions. In the limit of low particle velocities and magnetic fields, precise control of the particle motion and long storage times in the trap can provide ideal conditions for both gravitational, optical and hyperfine spectroscopy: for the sensitive verification of the equivalence principle for antihydrogen atoms; for increasing the accuracy of optical and hyperfine spectroscopy of atoms and antiatoms; for improving constraints on extra fundamental interactions from experiments with neutrons, atoms and antiatoms.
