项目摘要

Nuclear matter is at the heart of all visible matter in our universe. While it is known to be built from fundamental particles called quarks and gluons, precisely how the structures and properties of nuclear matter arise from the quarks and gluons remains a big question in fundamental physics. An important way to explore the question is through nuclear collision experiments, ongoing at the Relativistic Heavy Ion Collider (RHIC) and the Large Hadron Collider (LHC), that create a hot "subatomic soup" called quark-gluon plasma (QGP). This project helps understand the QGP by examining its behavior under extremely strong magnetic and vorticity fields. The PI accomplishes this by developing the theoretical description of QGP spin transport under such fields, performing phenomenological simulations to calculate observables, and analyzing the implications from comparison with experimental data. In addition to extracting QGP properties from such study, which is one of the major frontiers in today’s nuclear science, this project provides opportunities for engaging and mentoring graduate and undergraduate students in research as well as for carrying out a variety of public outreach activities. The objective of this project is to investigate novel transport arising from interplay between microscopic particle spin and macroscopic chirality, vorticity and magnetic fields of the bulk matter created in heavy ion collisions. The first component is to quantitatively understand the so-called chiral magnetic effect and associated background correlations. This is done by utilizing the anomalous-viscous fluid dynamics simulation framework, with an emphasis on analyzing the influence of initial nuclear structure inputs. The goal is to achieve an explanation of the latest high-precision isobar collision measurements as well as a coherent interpretation for the signal/background evolution from isobar to gold-gold collisions. The second component aims to advance the hydrodynamic framework with angular momentum as well as to phenomenologically compute spin polarization observables using a combination of hydrodynamic and transport models for a wide range of beam energies. The results offer insights into the latest STAR and HADES data at a few GeV collision energy as well as the similarity and difference between low and high energy collisions. More broadly, the project outcome helps expand our knowledge frontier on spin quantum transport under chirality, vorticity, and magnetic fields for general many-body systems across different disciplines.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.
核物质是我们宇宙中所有可见物质的核心。虽然它是由称为夸克和胶子的基本粒子构成的,但核物质的结构和性质如何从夸克和胶子中产生仍然是基础物理学中的一个大问题。探索这个问题的一个重要方法是通过相对论重离子对撞机(RHIC)和大型强子对撞机(LHC)正在进行的核碰撞实验,这些实验产生了一种称为夸克胶子等离子体(QGP)的热“亚原子汤”。该项目通过研究QGP在极强磁场和涡度场下的行为来帮助理解QGP。PI通过发展QGP自旋输运的理论描述来实现这一点,进行唯象模拟来计算观测值,并分析与实验数据比较的影响。除了从这样的研究中提取QGP属性,这是当今核科学的主要前沿之一,该项目还提供了参与和指导研究生和本科生进行研究以及开展各种公共宣传活动的机会。 本项目的目标是研究重离子碰撞中产生的微观粒子自旋与宏观手征性、涡度和大块物质磁场之间的相互作用所产生的新输运。第一部分是定量地理解所谓的手征磁效应和相关的背景相关性。这是通过利用粘性流体动力学模拟框架,重点分析初始核结构输入的影响。我们的目标是实现最新的高精度等压碰撞测量的解释,以及从等压到金-金碰撞的信号/背景演化的一致性解释。第二部分的目的是推进流体动力学框架与角动量,以及唯象计算自旋极化可观的流体动力学和运输模型的组合,用于广泛的光束能量。这些结果提供了对最新的星星和HADES数据在几个GeV的碰撞能量,以及低和高能量碰撞之间的相似性和差异的见解。更广泛地说,该项目的成果有助于扩大我们的知识前沿的旋性,涡度和磁场下的一般多体系统在不同学科的自旋量子输运。这一奖项反映了NSF的法定使命,并已被认为是值得通过评估使用基金会的智力价值和更广泛的影响审查标准的支持。
