量子完整统一理论

A Unified Theory of Quantum Holonomies

Atushi Tanaka, Taksu Cheon

摘要:

量子系统的慢环境参数的周期性变化诱导量子完整性。相位全息学就是一个著名的例子。另一种是更奇特的一种,表现出特征值和特征空间完整性。我们介绍了一个理论公式,描述了相位和本征空间holonomies在平等的基础上。该理论的基石是一个有序基的规范连接,它在概念上不同于Mead-Truhlar-Berry连接及其Wilczek-Zee扩展。基于Fujikawa的形式,发展了本征空间完整性的规范不变处理。绝热量子holonomy的例子,包括奇异的光谱简并,显示。

英文摘要:

A periodic change of slow environmental parameters of a quantum system induces quantum holonomy. The phase holonomy is a well-known example. Another is a more exotic kind that exhibits eigenvalue and eigenspace holonomies. We introduce a theoretical formulation that describes the phase and eigenspace holonomies on an equal footing. The building block of the theory is a gauge connection for an ordered basis, which is conceptually distinct from Mead-Truhlar-Berry's connection and its Wilczek-Zee extension. A gauge invariant treatment of eigenspace holonomy based on Fujikawa's formalism is developed. Example of adiabatic quantum holonomy, including the exotic kind with spectral degeneracy, are shown.
