定域物质与狄拉克场的几何

Localized Matter and Geometry of the Dirac Field

Alexander Makhlin

摘要:

在经典场论的框架内,讨论了作为物质场的狄拉克场与时空度规之间的联系。狄拉克场的极化结构被证明是丰富的,足以确定当地的时空度规,并解释所观察到的问题出现本地化的波形。的波形的本地化解释为本地时间减速和洛伦兹收缩的结果,作为一个动态的波形在其加速过程中的重新塑造。提出了一个定义的质量作为一个极限曲率的旋量诱导度规。提出了真空是狄拉克场的均匀分布的单位不变密度,并明确保持光锥的不变性的观点。定性解释所观察到的电荷不对称的本地化动力学的后果。经典的π介子场作为应力,质量和电荷通量的狄拉克场的局部波形的表现。碰撞物体的有限尺寸的高能过程的一些影响进行了讨论。提出了一个假设,即已知的内部自由度是局部时空(角)坐标,在黎曼几何中没有精确的对应物。

英文摘要:

Within the framework of classical field theory, the connection between the Dirac field as the field of matter and the spacetime metric is discussed. Polarization structure of the Dirac field is shown to be rich enough to determine the spacetime metric locally and to explain the emergence of observed matter as localized waveforms. The localization of the waveforms is explained as the result of the local time slowdown and the Lorentz contraction as a dynamic re-shaping of the waveforms in the course of their acceleration. A definition of mass as a limiting curvature of the spinor-induced metric is proposed. A view of the vacuum as a uniformly distributed unit invariant density of the Dirac field with an explicitly preserved invariance of the light cone is brought forward. Qualitative explanation of the observed charge asymmetry as the consequence of the dynamics of localization is given. The classical pion field is obtained as a manifestation of stresses, mass and charge flux in localized waveforms of the Dirac field. Some implications of the finite size of colliding objects for high-energy processes are discussed. A hypothesis that known internal degrees of freedom are the local spacetime (angular) coordinates that have no precise counterparts in Riemannian geometry is proposed.
