我们证明了Goldstone定理在宇称时间对称场论中的推广,证实了在非厄米模型中通过有效势的最小化而自发出现的场真空期望值伴随着无质量的标量玻色子.为我们的分析奠定了基础,我们首先展示了如何传统的量子场论的路径积分公式的量子化可以一直扩展到一个非厄米模型的共轭,而不是厄米共轭。将戈德斯通定理推广到非对称场论是因为存在一个守恒流,但它并不对应于非厄米拉格朗日量的对称性。除了延长戈德斯通定理的证明非对称理论,我们展示了一个具体的例子中,我们验证了存在的无质量玻色子在树和一个循环的水平。
We demonstrate the extension to parity-time ()-symmetric field theories of the Goldstone theorem, confirming that the spontaneous appearance of a field vacuum expectation value via minimization of the effective potential in a non-Hermitian model is accompanied by a massless scalar boson. Laying a basis for our analysis, we first show how the conventional quantization of the path-integral formulation of quantum field theory can be extended consistently to a non-Hermitian model by consideringconjugation instead of Hermitian conjugation. The extension of the Goldstone theorem to a-symmetric field theory is made possible by the existence of a conserved current that does not, however, correspond to a symmetry of the non-Hermitian Lagrangian. In addition to extending the proof of the Goldstone theorem to a-symmetric theory, we exhibit a specific example in which we verify the existence of a massless boson at the tree and one-loop levels.
