Anisotropic inflation from supergravity

已知标量场与规范场的动力学项之间存在非平凡耦合。基于这一事实，我们发现了一种新的暴胀情景，即所谓的各向异性暴胀。我们成功地阐明了宇宙微波温度涨落中统计各向异性的存在以及温度涨落与极化之间的相互关系。虽然由于普朗克团队的数据发布延迟，我们无法用宇宙学数据证明我们的模型，但我相信，通过来自早期宇宙的宇宙学数据，我们为探索自然的基本理论打开了一扇新的窗口。

It is known that there exists a non-trivial coupling between scalar fields and kinetic terms of gauge fields. Based on this fact, we found a novel inflationary scenario, the so-called anisotropic inflation. We succeeded in clarifying the existence of the statistical anisotropy in the cosmic microwave temperature fluctuations and the cross correlation between the temperature fluctuations and polarizations. Although we could not prove our model using cosmological data due to the delay of the data release by the Planck team, I am sure we opened a new window for exploring fundamental theory of nature through the cosmological data stemmed from the early universe.
