非微扰量子修正
Nonperturbative quantum corrections
摘要:
考虑了基于非结合分量上量子场算符的非结合分解的非微扰量子化过程。通过计算场算符的非线性函数的期望值,证明了这种方法产生了量子修正。这种修正原则上可以用力的半径、非定域物体的特征长度、与度规的连接不相容等来度量。结果表明,从一定形式的引力电耦合的量子校正导致消失的点电荷的奇异性,包括无限的自能。
英文摘要:
A nonperturbative quantization procedure based on a nonassociative decomposition of quantum field operators on nonassociative constituents is considered. It is shown that such approach gives rise to quantum corrections by calculations of expectation values of nonlinear functions of field operators. The corrections can in principle be measured as a radius of a force, characteristic length of nonlocal objects, the failure of connection compatibility with metric, and so on. The system of gravity interacting with Maxwell electromagnetism is considered. It is shown that quantum corrections from gravitoelectric coupling of a certain form leads to vanishing singularities of a point charge, including infinite self-energy.
