背景独立量化和不确定原理

Background independent quantization and the uncertainty principle

Golam Mortuza Hossain, Viqar Husain, Sanjeev S. Seahra

摘要:

结果表明,聚合物量子化导致一个修改后的不确定原理类似于从弦论和非交换几何。当应用于一般背景时空的量子场论时,对不确定原理的修正获得了度规依赖性。对于Friedmann-Robertson-Walker宇宙学来说,这转化为一个比例因子依赖性,它在早期宇宙中产生了很大的影响。

英文摘要:

It is shown that polymer quantization leads to a modified uncertainty principle similar to that obtained from string theory and non-commutative geometry. When applied to quantum field theory on general background spacetimes, corrections to the uncertainty principle acquire a metric dependence. For Friedmann-Robertson-Walker cosmology this translates to a scale factor dependence which gives a large effect in the early universe.
