自旋网络的退相干历史

Decoherent Histories of Spin Networks

David P. B. Schroeren

摘要:

由格里菲斯、盖尔曼和哈特尔发展的退相干历史形式主义是一个一般的框架,在这个框架中,我们可以建立一个永恒的、“广义的”量子理论,并从中提取预言。在本文中,我提出了一个退相干功能圈重力和解释现有的结果表明,粗粒度的历史遵循准经典轨迹在适当的限制。

英文摘要:

The decoherent histories formalism, developed by Griffiths, Gell-Mann, and Hartle is a general framework in which to formulate a timeless, `generalised' quantum theory and extract predictions from it. Recent advances in spin foam models allow for loop gravity to be cast in this framework. In this paper, I propose a decoherence functional for loop gravity and interpret existing results as showing that coarse grained histories follow quasiclassical trajectories in the appropriate limit.
