转动和Bogoliubov变换在中微子混合中的作用
On the role of the rotations and Bogoliubov transformations in neutrino mixing
摘要:
我们发现,混合变换狄拉克场产生的结果之间的非平凡的相互作用的旋转和Bogoliubov变换在梯子运营商的水平。事实上,这种变换的代数生成元之间的非交换性是味表象和质量表象以及相关真空结构的酉不等价性的原因。一个可能的热力学解释也进行了研究。
英文摘要:
We show that mixing transformations for Dirac fields arise as a consequence of the non-trivial interplay between rotations and Bogoliubov transformations at level of ladder operators. Indeed the non-commutativity between the algebraic generators of such transformations turns out to be responsible of the unitary inequivalence of the flavor and mass representations and of the associated vacuum structure. A possible thermodynamic interpretation is also investigated.
