AI 中文摘要
我们提出了一种热力学自洽的框架，用于将互补模型融合为多维量子色动力学（QCD）物态方程。在固定温度和重子化学势下，通过最小化单一巨势确定内部混合变量，确保热力学一致性与稳定性。组分间的相互作用可实现 crossover（交叉相变）、临界点及一阶相变。作为原理验证，我们将量子范德华强子共振气体模型与全息爱因斯坦-麦克斯韦-伸缩子模型融合，所得物态方程在各区域重现了恰当的描述，与现有格点QCD结果吻合良好，适用于宽温度和重子化学势范围内的重离子现象学研究。
英文摘要
We present a thermodynamically consistent framework for merging complementary models into a multidimensional QCD equation of state. An internal mixing variable is determined by minimizing a single grand potential at fixed temperature and baryon chemical potential, ensuring thermodynamic consistency and stability. Interactions between the components allow for a crossover, a critical endpoint, and a first-order transition. As a proof of principle, we merge a quantum van der Waals hadron-resonance-gas model with a holographic Einstein--Maxwell--Dilaton model. The resulting equation of state reproduces the appropriate description in each regime, agrees well with available lattice-QCD results, and is suitable for heavy-ion phenomenology over a broad range of temperature and baryon chemical potential.
