矩阵值Berezin-Toeplitz量化

A matrix-valued Berezin-Toeplitz quantization

S. Twareque Ali, Miroslav Engliš

摘要:

我们推广了一些较早的结果Berezin-Toeplitz类型的量子化希尔伯特空间建立在某些矩阵域。在目前,更广泛的设置,该理论可以适用于系统拥有几个运动和内部的自由度。我们的分析导致这些观测值的识别,在这个一般的情况下,承认一个半经典的限制和那些没有这样的限制存在。事实证明,后一类可观测量以内在的方式涉及内部自由度。在数学上,作为标准Berezin-Toeplitz量化的推广,该理论指出了将这种量化技术应用于可能的非交换空间的方法,以至于相空间中的点现在被$N\times N$矩阵取代。

英文摘要:

We generalize some earlier results on a Berezin-Toeplitz type of quantization on Hilbert spaces built over certain matrix domains. In the present, wider setting, the theory could be applied to systems possessing several kinematic and internal degrees of freedom. Our analysis leads to an identification of those observables, in this general context, which admit a semi-classical limit and those for which no such limit exists. It turns out that the latter class of observables involve the internal degrees of freedom in an intrinsic way. Mathematically, the theory, being a generalization of the standard Berezin-Toeplitz quantization, points the way to applying such a quantization technique to possibly non-commutative spaces, to the extent that points in phase space are now replaced by $N\times N$ matrices.
