相干态球的量子化

Quantization of the sphere with coherent states

Marc Lachieze Rey, Jean-Pierre Gazeau, Eric Huguet, Jacques Renaud, Tarik Garidi

摘要:

利用相干态的量子化允许“扩展“参数的任何空间X。在X是相空间的情况下,这导致了通常的量子力学。但是这个过程要一般得多,并且不需要辛,或者X中除了测度之外的任何类型的结构。它被简单地认为是看待系统的不同方式,分辨率的选择,与数据处理类似,其中相干态(例如,在小波的形式下)是非常有效的。在这里,我们提出了2-球的复相干态量子化,重点是与群表示的联系。我们展示了如何自然地导致这个过程的模糊领域和非交换几何。

英文摘要:

Quantization with coherent states allows to " quantize " any space X of parameters. In the case where X is a phase space, this leads to the usual quantum mechanics. But the procedure is much more general, and does not require a symplectic, or any kind of structure in X, other than a measure. It is simply considered as a different way to look at the system, the choice of a resolution, in analogy with data handling, where coherent states (e.g., under the form of wavelets) are very efficient. Here, we present the complex coherent states quantization of the 2-sphere, with emphasis on the links with group representation. We show how this procedure leads naturally to the fuzzy sphere and to non commutative geometry.
