时空非对易性的非Pauli跃迁

Non-Pauli Transitions From Spacetime Noncommutativity

A. P. Balachandran, Anosh Joseph, Pramod Padmanabhan

摘要:

我们有充分的理由怀疑普朗克尺度下的时空是非对易的。典型地,这种非对易性由具有数值项的固定“向量”或“张量”控制。对于Moyal时空,它是反对称矩阵$θ_{μν}$。在实施庞加莱不变性的方法中,这些变形或扭曲了相同粒子状态矢量的(反)对称化方法。我们认为,地球的旋转和运动在宇宙中的“突然”事件的保利禁止过程。他们诱导(扭曲)玻色子组件在状态矢量相同的旋粒子在扭曲的存在下。这些成分引起非泡利跃迁。从已知的限制,这样的过渡,我们推断,非对易性的能量标度是$\gtrsim 10^{24}\textrm{TeV}$。这意味着一种新的能量尺度超越了普朗克尺度。

英文摘要:

There are good reasons to suspect that spacetime at Planck scales is noncommutative. Typically this noncommutativity is controlled by fixed "vectors" or "tensors" with numerical entries. For the Moyal spacetime, it is the antisymmetric matrix $θ_{μν}$. In approaches enforcing Poincaré invariance, these deform or twist the method of (anti-)symmetrization of identical particle state vectors. We argue that the earth's rotation and movements in the cosmos are "sudden" events to Pauli-forbidden processes. They induce (twisted) bosonic components in state vectors of identical spinorial particles in the presence of a twist. These components induce non-Pauli transitions. From known limits on such transitions, we infer that the energy scale for noncommutativity is $\gtrsim 10^{24}\textrm{TeV}$. This suggests a new energy scale beyond Planck scale.
