翘曲六维超引力的动力学解

Dynamical solutions of warped six dimensional supergravity

Edmund J. Copeland, Osamu Seto

摘要:

本文在一个扭曲的六维超引力模型中导出了一类新的含时精确解。在我们对底层模场的形式所做的假设下,我们证明了唯一一致的时间依赖解导致所有六个维度随时间演化,这意味着额外维度的最终解压缩或崩溃。我们还展示了动态如何影响赤字角的量化。

英文摘要:

We derive a new class of exact time dependent solutions in a warped six dimensional supergravity model. Under the assumptions we make for the form of the underlying moduli fields, we show that the only consistent time dependent solutions lead to all six dimensions evolving in time, implying the eventual decompactification or collapse of the extra dimensions. We also show how the dynamics affects the quantization of the deficit angle.
