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.

该奖项为肯尼恩学院的副教授约翰·T·吉布林（John T. Giblin，Jr。）的研究提供资金。最近的观察结果和实验结果已经对早期宇宙的高能粒子物理和模型的性质进行了新的启示。 现在比以往任何时候都更清楚，宇宙是我们唯一可以在加速器中以高于能量的能量研究基本物理学的实验室。 在这些能量上描述物理的理论是高度非线性的，复杂的动力学系统。 吉布林教授的研究将使用最先进的数值技术以及分析方法来预测许多高能物理学模型的观察结果。 这些结果将有助于了解当前和未来的观察如何限制超出标准模型物理的模型。这项研究还解决了在年轻学生和大学本科生中培养对科学兴趣的迫切需求。大约有2000名中学生将被带到肯尼恩学院，参加“科学星期六”计划，该计划将与他们进行科学活动。学生还将全天与科学家一起工作，为他们提供积极的互动科学探究模型。这笔资金还将支持本科研究和协作。有意义的本科研究是支持和培养下一代年轻科学家的关键组成部分。根据该奖项研究的数值方法将允许研究非线性和衍生耦合的现场理论，因为它们与通货膨胀，衡量理论和重力有关。此处开发的软件，网格和气泡Evolver（GABE）将发现阿贝尔和非阿贝尔仪表场如何修改通货膨胀和通货膨胀后的过程，并使用非最小动力学术语探测现场理论的影响。 此外，它将用于预测这些模型的可观察到的特征，原始功率谱和重力辐射。这些研究将有助于理解通货膨胀的现实模型是否可行并与观察结果一致，并探索颗粒的非最小性性质，以解释黑暗能量的性质。此外，该奖项将支持对通货膨胀后时期和相关数值期间非线性重力相互作用的研究。 当我们为下一代引力波观测站做准备时，重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后果。
