导致自然正规序的场的C-对称量子化

C-symmetric quantization of fields leading to a natural normal ordering

Zahid Zakir

摘要:

在量子化场时,由于时间反演的非线性性质,负频率模的创生-湮灭算符不应直接在场算符中,而应在算符乘积中代替为反粒子算符。对于标准的最小拉格朗日函数(不对称下的复杂的共轭领域),它示出的电荷共轭(C-)的对称性条件的哈密顿量和电荷运营商导致的身份的运营商产品允许一个取代负频率运营商产品的正频率。同时,观测量中的算符变得正常有序,零点能量不出现。只有场算符下的对称化的拉格朗日量才导致零点能。讨论了这种场的C对称量子化的实验对抗和某些真空能量问题的解决。

英文摘要:

At the quantization of fields, due to the non-linear character of the time reversal, the creation-annihilation operators for the negative frequency modes should be replaced to the operators of antiparticles not directly in the field operators, but in the operator products. For the standard minimal Lagrangians (asymmetrical under the complex conjugated fields) it is shown that the charge conjugation (C-) symmetry conditions for the Hamiltonian and the charge operator lead to the identities for the operator products allowing one to replace the negative frequency operator products to the positive frequency ones. At the same time the operators in observables become normal ordered and the zero-point energy does not appear. Only the symmetrized under the field operators Lagrangians lead to the zero-point energy. The confrontation by the experiments of the such C-symmetric quantization of fields and the solution some of the vacuum energy problems are discussed.
