Gravitational Duals from Equations of State II: Large Hierarchies and False Vacua
- 基于物理信息神经网络,从边界热力学数据反推全息标量势
- 成功重建虚假真空区的势能函数,数值稳定性优异
- 为强耦合系统研究提供数据驱动新范式,适合高能物理与计算引力研究者
我们研究在存在大能标层次和虚假真空的背景下,强耦合量子场论全息对偶的重构问题。在规范/引力对偶框架下,这些特征对应于非平凡的热力学行为和奇异的重整化群流,包括跳过非相邻固定点的跃迁。基于先前基于物理信息神经网络(PINNs)的工作,我们将全息逆问题——从边界热力学数据重构体内部标量势——扩展至这一新物理区域。该设置带来诸多概念与数值挑战,如近简并态、显著的能量尺度差异,以及输入数据未直接探测的势能区域。我们提出一系列方法改进,克服上述障碍,提升了现有基于PINNs的方法,并将其拓展至此前难以触及的物理新域。应用该框架,我们在虚假真空区域实现了标量势的高精度重构,尽管存在严重数值刚性,仍与底层热力学物理特征保持稳健一致。结果深化了全息与机器学习的联系,表明数据驱动方法可为强耦合系统结构提供新洞见。
原文摘要 · Abstract (English)
We investigate the reconstruction of holographic duals for strongly coupled quantum field theories in regimes characterized by large hierarchies and the presence of false vacua. Within the gauge/gravity duality, these features translate into non-trivial thermodynamic behaviour and exotic renormalization group flows, including skipping flows between non-adjacent fixed points. Building on previous work based on Physics-Informed Neural Networks (PINNs), we extend the holographic inverse problem of reconstructing the bulk scalar potential from boundary thermodynamic data into this new regime. This setting presents a variety of conceptual and numerical challenges, such as near-degenerate states, large hierarchies of energy scales, and regions of the potential that are not directly probed by the input data. We develop a set of methodological advances that overcome these obstacles, thereby improving the established PINNs-based methodology and extending it to new physical regimes of interest that were previously out of reach. Applying the developed framework, we demonstrate accurate reconstruction of scalar potentials deep into the false vacuum regime, achieving robust agreement with the physical features of the underlying thermodynamics despite significant numerical stiffness. Our results extend the bridge between holography and machine learning, and suggest that data-driven approaches can provide new insights into the structure of strongly coupled systems.
