从永恒的通货膨胀中平稳退出?

A Smooth Exit from Eternal Inflation?

S. W. Hawking, Thomas Hertog

摘要:

通常的通货膨胀理论在永恒的通货膨胀中崩溃了。我们得到了一个双重描述的永恒的通货膨胀的变形欧几里得CFT位于永恒的通货膨胀的阈值。配分函数给出了无边界状态下阈值面不同几何形状的振幅。它的局部和全局行为的双重玩具模型表明,振幅是低的表面,这是不接近共形的圆形三球面和基本上为零的表面与负曲率。基于这一点,我们推测,从永恒的通货膨胀的出口不会产生一个无限的分形样的多元宇宙,但有限的,合理的光滑。

英文摘要:

The usual theory of inflation breaks down in eternal inflation. We derive a dual description of eternal inflation in terms of a deformed Euclidean CFT located at the threshold of eternal inflation. The partition function gives the amplitude of different geometries of the threshold surface in the no-boundary state. Its local and global behavior in dual toy models shows that the amplitude is low for surfaces which are not nearly conformal to the round three-sphere and essentially zero for surfaces with negative curvature. Based on this we conjecture that the exit from eternal inflation does not produce an infinite fractal-like multiverse, but is finite and reasonably smooth.
