在经典力学和量子力学中实现完整约束

Realizing holonomic constraints in classical and quantum mechanics

Richard Froese, Ira Herbst

摘要:

我们考虑的问题,约束粒子的配置空间的一个子流形Sigma使用一系列的增长潜力。我们比较了这个过程的经典和量子版本。这导致了两种情况下的新结果:经典情况下的无界能量定理和量子平均定理。我们的两个步骤的方法,包括膨胀参数的扩展,然后在正常方向上的平均值,强调了正常的Sigma束的作用,并显示当限制相空间将比预期的更大(或不同)。

英文摘要:

We consider the problem of constraining a particle to a submanifold Sigma of configuration space using a sequence of increasing potentials. We compare the classical and quantum versions of this procedure. This leads to new results in both cases: an unbounded energy theorem in the classical case, and a quantum averaging theorem. Our two step approach, consisting of an expansion in a dilation parameter, followed by averaging in normal directions, emphasizes the role of the normal bundle of Sigma, and shows when the limiting phase space will be larger (or different) than expected.
