The proposed research involves exploring novel connections between cosmology and the new physics beyond the Standard Model. The PI plans to use the Cosmic Microwave Background as a probe of the new physics near the scale of inflation that could leave a small, but detectable, imprint in the CMB anisotropy. The PI proposes a new explanation for the Type IA supernovae observations, which are postulated to be fainter because of dynamical conversion of photons into axions, without cosmic acceleration. The PI predicts a new particle, the ultralight axion instead of the assumption of dark energy to explain these observations. The PI also proposes to investigate whether the dynamics of extra dimensions can generate the primordial seed for extra-galactic magnetic fields. The PI also intends to apply techniques from statistical physics to understand the transmission of information in neurons.

这项拟议的研究涉及探索宇宙学和超越标准模型的新物理学之间的新联系。PI计划使用宇宙微波背景作为新物理的探测器，接近膨胀的规模，这可能会在CMB的各向异性中留下一个小的但可检测的印记。PI对IA型超新星的观测提出了一种新的解释，这种超新星被认为是由于光子到轴子的动力学转换而变得更暗，而没有宇宙加速。PI预测了一种新的粒子，即超轻轴子，而不是暗能量假设来解释这些观察到的结果。PI还建议研究额外维度的动力学是否可以产生银河系外磁场的原始种子。PI还打算应用统计物理学的技术来理解神经元中的信息传输。
