非对易时空上的$\mathcal{PT}$ -对称量子场论

$\mathcal{PT}$-symmetric quantum field theory on the noncommutative spacetime

Oleg O. Novikov

摘要:

考虑了具有角扭曲的非对易时空的$\mathcal{PT}$对称量子场论,构造了它的伪厄米解释。我们探讨的角度扭曲的背景下,内部和空间宇称之间的差异,对于后者,我们发现新的$\mathcal{PT}$对称的相互作用,是非平凡的非对易时空。对于等价厄米特模型的首阶$T$矩阵,我们再现了与先前在对易时空上的量子场论中得到的公式相同的公式。这个公式意味着,如果在非厄米特公式中不破坏非对易几何的对称性,则首阶散射振幅保持非对易几何的对称性。

英文摘要:

We consider the $\mathcal{PT}$-symmetric quantum field theory on the noncommutative spacetime with angular twist and construct its pseudo-Hermitian interpretation. We explore the differences between internal and spatial parities in the context of the angular twist and for the latter we find new $\mathcal{PT}$-symmetric interactions that are nontrivial only for the noncommutative spacetime. We reproduce the same formula for the leading order $T$-matrix of the equivalent Hermitian model as the one obtained earlier for the quantum field theory on the commutative spacetime. This formula implies that the leading order scattering amplitude preserves the symmetries of the noncommutative geometry if they are not broken in the non-Hermitian formulation.
