项目摘要

Just a few microseconds after the Big Bang, the Quark-Gluon Plasma permeated our universe. This phase of strongly interacting matter exists under extreme conditions of temperatures or densities, like the ones achieved in ultra-relativistic heavy ion collisions currently taking place at the Relativistic Heavy Ion Collider (RHIC) and the Large Hadron Collider (LHC), or the ones realized in nature in the core or neutron stars or their mergers. This project will advance our knowledge of hot and dense strongly interacting matter by calculating observables from first principles and relating them to measurements. The PI will investigate effects which, if verified, could change our understanding of the deconfinement phase transition and strongly interacting matter. The high precision now achievable in the theoretical calculations allows such a combined effort between theory and experiment for the first time. The project will contribute to training the next generation of students working on the theory of fundamental interactions, both at the undergraduate and graduate levels. The PI will promote physics to underrepresented minorities through public lectures, seminars and visits to Houston schools. She will work with associations of underrepresented students to develop a program to recruit undergraduate and graduate students at UH. The purpose of this project is to significantly advance our understanding of strongly interacting matter by means of first principle lattice simulations, complemented by phenomenological approaches, to build a bridge between theory and experiment. The PI plans to achieve this goal by calculating several observables from first principles: conserved charge fluctuations to connect to heavy-ion experiments, Equation of State at finite baryonic and strangeness density for the first time; inclusion of a critical point with the correct features for QCD. The methodology is to calculate relevant observables using numerical simulations from first principles. These observables can then either be directly compared to experimental results from RHIC and the LHC, or they can be used as inputs into phenomenological models for the evolution of heavy-ion collisions or neutron star mergers. Finally, some of them can be used to improve phenomenological models through parameter or interaction constraints. The Quark-Gluon Plasma exhibits several features in common to other strongly interacting systems, such as ultra-cold atom gases in a magneto-optical trap. Thus, the study of hot and dense QCD matter will yield novel insight into a class of physical systems, not limited to the domain of nuclear physics.This project advances the objectives of "Windows on the Universe: the Era of Multi-Messenger Astrophysics", one of the 10 Big Ideas for Future NSF Investments.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
就在宇宙大爆炸后的几微秒内,夸克-胶子等离子体弥漫在我们的宇宙中。这种强相互作用物质的阶段存在于极端的温度或密度条件下,就像目前在相对论重离子对撞机(RHIC)和大型强子对撞机(LHC)上发生的超相对论重离子碰撞所实现的那样,或者在核心或中子星或它们的合并中实现的那种。该项目将通过从第一原理计算可观测值并将其与测量相关联,提高我们对热致密强相互作用物质的认识。PI将研究的影响,如果得到证实,可能会改变我们对非定义相变和强相互作用物质的理解。现在在理论计算中可以达到的高精度使得理论和实验第一次结合起来。该项目将有助于培养下一代从事基本相互作用理论研究的本科生和研究生。PI将通过公开讲座、研讨会和访问休斯顿的学校,向未被充分代表的少数族裔推广物理学。她将与代表性不足的学生协会合作,制定一项计划,在休斯敦大学招收本科生和研究生。该项目的目的是通过第一原理晶格模拟,辅以现象学方法,显著提高我们对强相互作用物质的理解,在理论和实验之间建立一座桥梁。PI计划通过计算第一性原理的几个观测值来实现这一目标:与重离子实验相关的守恒电荷波动,首次在有限重子和奇异密度下的状态方程;包含一个临界点与正确的特征为QCD。方法是利用第一性原理的数值模拟计算相关观测值。这些观测结果可以直接与RHIC和LHC的实验结果进行比较,或者它们可以用作重离子碰撞或中子星合并演化的现象学模型的输入。最后,其中一些可以通过参数约束或交互约束来改进现象学模型。夸克-胶子等离子体表现出与其他强相互作用系统(如磁光阱中的超冷原子气体)相同的几个特征。因此,对热而致密的QCD物质的研究将产生对一类物理系统的新见解,而不仅仅局限于核物理学领域。该项目推进了“宇宙之窗:多信使天体物理学时代”的目标,这是美国国家科学基金会未来投资的十大理念之一。该奖项反映了美国国家科学基金会的法定使命,并通过使用基金会的知识价值和更广泛的影响审查标准进行评估,被认为值得支持。
