四维广义相对论中非线性引力子的Kodama展开

Nonlinear gravitons in 4-D general relativity by expansion about the Kodama state

摘要:

本文利用非度规广义相对论的一种新描述,给出了彭罗斯非线性引力子思想的一种可能实现。为了解决围绕儿玉态的可正规化性及其作为引力基态的可靠性问题,我们扩展了儿玉态的涨落理论。这就产生了一个具有明确定义的希尔伯特空间结构的复引力理论,我们在线性化水平和完全非线性理论中都进行了量子化。本文的结果表明,保存的物理自由度的完全非线性理论下的线性化,以及提供一个希尔伯特空间的状态,前者湮灭的量子哈密顿约束。

英文摘要:

In this paper we provide a possible realization of Penrose's idea of nonlinear gravitons using a new description of nonmetric general relativity. In the addressal of issues surrounding the normalizability of the Kodama state and its reliability as a ground state for gravity, we expand the theory in fluctuations about the Kodama state. This produces a theory of complex gravity with a well-defined Hilbert space structure, whose quantization we carry out both at the linearized level and in the full nonlinear theory. The results of this paper demonstrate the preservation of the physical degrees of freedom of the full nonlinear theory under linearization, as well provide a Hilbert space of states of the former annihilated by the quantum Hamiltonian constraint.
