Burn-UD程序对强子-夸克物质相变的数值模拟
The Burn-UD code for the numerical simulations of the Hadronic-to-Quark-Matter phase transition
摘要：
Burn-UD是一个流体动力学燃烧程序，用于模拟强子物质到夸克物质的相变，特别适用于中子星的内部。Burn-UD模拟了界面两侧不同状态方程（EoS）的火焰微观物理，即灰烬（上下奇异夸克相）和燃料（上下夸克相）。它还允许用户探索由不同过程产生的奇怪夸克种子，包括中子星内部的DM湮灭。模拟提供了一个物理窗口，以诊断燃烧过程是否会安静而缓慢地沸腾，导致从爆燃到爆震或（夸克）核心坍塌爆炸的过渡。这种高能相变（夸克新星）将在高能天体物理学中产生影响，并有助于我们理解许多仍然神秘的天体物理瞬变。此外，对不同初始态的相变动力学有一个精确的理解，可以帮助进一步限制一般QCD的非微扰机制的性质。我们希望Burn-UD将发展成为一个平台/软件，供QCD社区使用和共享，探索夸克物质的阶段和天体物理学家在致密星上工作。
英文摘要：
Burn-UD is a hydrodynamic combustion code used to model the phase transition of hadronic to quark matter with particular application to the interior of neutron stars. Burn-UD models the flame micro-physics for different equations of state (EoS) on both sides of the interface, i.e. for both the ash (up-down-strange quark phase) and the fuel (up-down quark phase). It also allows the user to explore strange quark seeding produced by different processes including DM annihilation inside neutron stars. The simulations provide a physical window to diagnose whether the combustion process will simmer quietly and slowly, lead to a transition from deflagration to detonation or a (quark) core-collapse explosion. Such an energetic phase transition (a Quark-Nova) would have consequences in high-energy astrophysics and could aid in our understanding of many still enigmatic astrophysical transients. Furthermore, having a precise understanding of the phase transition dynamics for different EoSs could aid further in constraining the nature of the non-perturbative regimes of QCD in general. We hope that Burn-UD will evolve into a platform/software to be used and shared by the QCD community exploring the phases of Quark Matter and astrophysicists working on Compact Stars.
