GRANIT计划：UCN引力量子态的陷阱
GRANIT project: a trap for gravitational quantum states of UCN
摘要：
以前对超冷中子引力束缚态的研究表明了能级的量子化，并证实了量子力学对两个最低能态波函数平均大小的预测。类似位置测量的改进只能将精度提高一个数量级。因此，我们开发了另一种方法，包括精确测量的能级。GRANIT实验致力于研究由振荡微扰引起的量子态之间的共振跃迁。根据海森堡的测不准关系，测量能级的准确性受到可用于执行跃迁的时间的限制。因此，捕获量子态将是必要的，并且必须控制每个损耗源以使状态的寿命最大化。本文讨论了量子态之间跃迁的一般原理，并考虑了中子在阱中的主要系统损失。
英文摘要：
Previous studies of gravitationally bound states of ultracold neutrons showed the quantization of energy levels, and confirmed quantum mechanical predictions for the average size of the two lowest energy states wave functions. Improvements in position-like measurements can increase the accuracy by an order of magnitude only. We therefore develop another approach, consisting in accurate measurements of the energy levels. The GRANIT experiment is devoted to the study of resonant transitions between quantum states induced by an oscillating perturbation. According to Heisenberg's uncertainty relations, the accuracy of measurement of the energy levels is limited by the time available to perform the transitions. Thus, trapping quantum states will be necessary, and each source of losses has to be controlled in order to maximize the lifetime of the states. We discuss the general principles of transitions between quantum states, and consider the main systematical losses of neutrons in a trap.
