广义相对论的协变远程平行等价哈密顿方程

Hamilton's equations in the covariant teleparallel equivalent of general relativity

Laxmipriya Pati, Daniel Blixt, Maria-Jose Guzman

摘要:

我们提出了广义相对论(TEGR),这是一个重新制定的广义相对论的基础上的无曲率,度量兼容,和扭曲的连接远程平行的汉密尔顿方程。为此,我们考虑通过向量,反对称,对称和无迹,和跟踪不可约的相空间变量的分解得到的TEGR的哈密顿量。我们提出的哈密顿TEGR在协变形式主义的文献中的第一次,通过考虑依赖于洛伦兹矩阵的自旋连接。我们介绍的数学形式主义计算汉密尔顿方程在Weitzenbock规范和协变的制定,后者,我们必须引入新的领域:洛伦兹矩阵及其相关的动量。我们还推导出明确的四分体的共轭动量和共轭动量的度量,传统上定义在GR,这是很重要的比较两种形式主义之间的关系。

英文摘要:

We present Hamilton's equations for the teleparallel equivalent of general relativity (TEGR), which is a reformulation of general relativity based on a curvatureless, metric compatible, and torsionful connection. For this, we consider the Hamiltonian for TEGR obtained through the vector, antisymmetric, symmetric and trace-free, and trace irreducible decomposition of the phase space variables. We present the Hamiltonian for TEGR in the covariant formalism for the first time in the literature, by considering a spin connection depending on Lorentz matrices. We introduce the mathematical formalism necessary to compute Hamilton's equations in both Weitzenbock gauge and covariant formulation, where for the latter we must introduce new fields: Lorentz matrices and their associated momenta. We also derive explicit relations between the conjugate momenta of the tetrad and the conjugate momenta for the metric that are traditionally defined in GR, which are important to compare both formalisms.
