论文摘要

在此贡献中,我们绘制了惠勒 - 迪维特方程的分支切割量子公式,分析持续到复杂平面。作为起点,我们将方法以重力的ho红叶叶菲兹的表述为基础,后者出于重新归一化的原因采用了较高的时空曲率术语。按照标准程序,通过提高哈密顿量来实现拉格朗日密度的量化,该动力变量代表了分支切开的复杂尺度因子和与操作员类别的共轭动量。我们到达具有非线性潜力的Schrödinger型方程。然后,获得解决方案并讨论不同的潜在参数化。结果加强了分支切割宇宙的收缩和扩展阶段之间的量子飞跃的概念,这与Bekenstein标准非常吻合。

In this contribution we sketch a branch-cut quantum formulation of the Wheeler-DeWitt equation analytically continued to the complex plane. As a starting point, we base our approach on the Hořava-Lifshitz formulation of gravity, which employs higher spatial-derivative terms of the spacetime curvature for renormalisation reasons. Following standard procedures, the quantization of the Lagrangian density is achieved by raising the Hamiltonian, the dynamical variable which represents the branch-cut complex scale factor and the conjugate momentum to the category of operators. We arrive at an Schrödinger-type equation with a non-linear potential. Solutions are then obtained and discussed for different potential parameterizations. The results reinforce the conception of a quantum leap between the contraction and expansion phases of the branch-cut universe, in good agreement with the Bekenstein criterion.
