This award funds the research of Associate Professor John T. Giblin, Jr. at Kenyon College. Recent observational and experimental results have shed new light on the nature of high-energy particle physics and models of the early Universe. It is clearer now than ever that the Universe is the only laboratory in which we can study fundamental physics at energies above those achievable in accelerators. The theories that describe physics at these energies are highly non-linear, complex dynamical systems. Professor Giblin's research will use employ cutting-edge numerical techniques as well as analytic methods to predict the observational consequences of many models of high-energy physics. These results will help understand how current and future observations can constrain models of beyond-the-standard model physics. This research also addresses the pressing need to cultivate interest in science among young students and college undergraduates. Approximately two hundred fifty middle school students will be brought to Kenyon College for a "Science Saturday" program that will engage them with hands on science activities. Students will also get to work with scientists throughout the day offering them a positive, interactive model of scientific inquiry. This funding will also support undergraduate research and collaboration. Meaningful undergraduate research is a critical component of supporting and cultivating the next generation of young scientists. The numerical methods studied under this award will allow for the study of non-linear and derivatively coupled field theories as they relate to Inflation, Gauge theories and Gravitation. The software developed here, Grid and Bubble Evolver (GABE), will discover how abelian and non-abelian gauge fields modify inflation and post-inflationary process and probe the effects of field theories with non-minimal kinetic terms. Further, it will be used to predict observable signatures, primordial power spectra and gravitational radiation, of these models. These studies will help to understand whether or not realistic models of inflation are viable and consistent with observations, and explore the non-minimal nature of particles as a possible explanation of the nature of Dark Energy. In addition, this award will support investigations of nonlinear gravitational interactions during phase transitions in the post-inflationary epoch and relevant numerical. As we prepare for the next generation of gravitational wave observatories, precise predictions of gravitational wave spectra could have drastic consequences on the design and cost of these experiments.

该奖项资助凯尼恩学院副教授 John T. Giblin, Jr. 的研究。最近的观测和实验结果为高能粒子物理和早期宇宙模型的本质提供了新的线索。 现在比以往任何时候都更加清楚的是，宇宙是唯一一个我们可以在高于加速器可达到的能量下研究基础物理的实验室。 描述这些能量物理的理论是高度非线性、复杂的动力系统。 吉布林教授的研究将利用尖端的数值技术和分析方法来预测许多高能物理模型的观测结果。 这些结果将有助于理解当前和未来的观测如何限制超出标准模型物理的模型。这项研究还解决了培养年轻学生和大学生对科学兴趣的迫切需要。大约 250 名中学生将被带到凯尼恩学院参加“科学星期六”计划，让他们参与科学活动。学生还将全天与科学家一起工作，为他们提供积极的、互动的科学探究模式。这笔资金还将支持本科生的研究和合作。有意义的本科研究是支持和培养下一代年轻科学家的重要组成部分。该奖项研究的数值方法将允许研究与暴胀、规范理论和万有引力相关的非线性和导数耦合场论。这里开发的软件 Grid and Bubble Evolver (GABE) 将发现阿贝尔和非阿贝尔规范场如何修改暴胀和后暴胀过程，并利用非最小动力学项探讨场论的影响。 此外，它将用于预测这些模型的可观测特征、原始功率谱和引力辐射。这些研究将有助于了解现实的暴胀模型是否可行并与观测结果一致，并探索粒子的非最小性质作为暗能量性质的可能解释。此外，该奖项还将支持后通货膨胀时代相变期间的非线性引力相互作用和相关数值的研究。 当我们为下一代引力波天文台做准备时，引力波谱的精确预测可能会对这些实验的设计和成本产生巨大的影响。
