量子-经典边界与物体的转动惯量
The quantum-classical boundary and the moments of inertia of physical objects
摘要：
在过去的几年里，一些研究提出存在一个阈值，将物体的经典行为与量子行为分开，该阈值取决于物体的大小和质量，以及通常与整个宇宙相关的某些属性。在这里，我们重新审视这些研究的结果和重铸的临界阈值的物理对象的惯性矩的阈值标准。惯性矩高于这个临界阈值的物理对象，就其作为整个对象的质心运动而言，预期必然以经典方式表现，而惯性矩低于这个阈值的物理对象可以表现出量子行为，除非被其他效应带入经典。与观测值的转动惯量的比较，并建议作为一个分类参数的转动惯量的量子与经典行为的检查对象中尺度域。
英文摘要：
During the last few years, several studies have proposed the existence of a threshold separating classical from quantum behavior of objects that is dependent on the size and mass of an object as well as being dependent on certain properties usually associated with the universe as a whole. Here, we reexamine the results of these studies and recast the threshold criteria in terms of a critical threshold value for the moments of inertia of physical objects. Physical objects having moments of inertia above this critical threshold value would be expected to behave necessarily in a classical manner in terms of their center of mass motion as entire objects, while physical objects having moments of inertia lower than this threshold value could exhibit quantum behavior unless brought into classicality by other effects. A comparison with observed values of moments of inertia is presented, and the moment of inertia is suggested as a classifying parameter for examination of the quantum versus classical behavior of objects in the mesoscale domain.
