模糊非交换SpaceTime:新世纪的新范式

Fuzzy, Non Commutative SpaceTime: A New Paradigm for a New Century

B. G. Sidharth

摘要:

20世纪的物理学,无论是经典的还是量子的,都是基于时空是可微流形的概念。虽然这项工作已经在标准模型中达到顶峰,但现在人们普遍认为,根据最近的实验结果,我们必须超越标准模型。另一方面,量子超弦理论和最近的量子化时空模型,例如,电子可以有意义地用克尔-纽曼度规描述,已经显示出希望。它们导致数学上相同的时空-能量-动量对易关系,以及事实上相同的非对易几何,这与通常的时空概念不同。这很可能成为新世纪的一个新范例。

英文摘要:

Much of twentieth century physics, whether it be Classical or Quantum, has been based on the concept of spacetime as a differentiable manifold. While this work has culminated in the standard model, it is now generally accepted that in the light of recent experimental results, we have to go beyond the standard model. On the other hand Quantum SuperString Theory and a recent model of Quantized Spacetime in which, for example, an electron can be meaningfully described by the Kerr-Newman metric, have shown promise. They lead to mathematically identical spacetime-energy-momenta commutation relations, and infact an identical non commutative geometry which is a departure from the usual concept of spacetime. This could well be a new paradigm for the new century.
