约束系统的一种新形式的准经典时空动力学揭示了如何从引力系统的正则量子化中系统地导出量子效应。这些准经典方法导致额外的领域，代表量子涨落和更高的时刻，这是耦合到经典度规领域。它们描述了非绝热量子动力学，并且可以被解释为场论中非局域量子修正的隐式公式。这个领域的理论方面的研究在这里第一次，适用于一个引力系统，一个易于处理的模型构建。在正则量子引力中，相关场的静态解可以以几乎封闭的形式得到，并揭示了势能近视界和渐近效应的新性质。
A new form of quasiclassical space-time dynamics for constrained systems reveals how quantum effects can be derived systematically from canonical quantization of gravitational systems. These quasiclassical methods lead to additional fields, representing quantum fluctuations and higher moments, that are coupled to the classical metric fields. They describe non-adiabatic quantum dynamics and can be interpreted as implicit formulations of non-local quantum corrections in a field theory. This field-theory aspect is studied here for the first time, applied to a gravitational system for which a tractable model is constructed. Static solutions for the relevant fields can be obtained in almost closed form and reveal new properties of potential near-horizon and asymptotic effects in canonical quantum gravity.
