经典到达时间的量子化及其动力学

Quantizations of the classical time of arrival and their dynamics

Eric A. Galapon, John Jaykel P. Magadan

摘要:

通过对经典到达时间关于自由到达时间的展开进行量子化,将经典到达时间量子化。量子化是制定在坐标表示,表示在两个变量的多项式函数的排序规则。这导致表示的量化时间的到达算子的积分算子,其内核是由所选择的排序规则。该制剂本身的泛化,允许建设的到达时间运营商,不能通过直接量化使用特定的排序规则。Wey,对称和Born-Jordan量子化进行了研究。不同的到达时间运营商的本征函数的动力学进行了研究。本征函数在其各自的本征值处表现出在预期到达点处的酉到达。

英文摘要:

The classical time of arrival in the interacting case is quantized by way of quantizing its expansion about the free time of arrival. The quantization is formulated in coordinate representation which represents ordering rules in terms of two variable polynomial functions. This leads to representations of the quantized time of arrival operators as integral operators whose kernels are determined by the chosen ordering rule. The formulation lends itself to generalization which allows construction of time of arrival operators that cannot be obtained by direct quantization using particular ordering rules. Wey, symmetric and Born-Jordan quantizations are specifically studied. The dynamics of the eigenfunctions of the different time of arrival operators are investigated. The eigenfunctions exhibit unitary arrival at the intended arrival point at their respective eigenvalues.
