资源简介:
This dataset accompanies the article <i>Cosmic Evolution under Tension-Driven Potentials: A Unified Formalism</i>.<br>It contains the full Python implementation of the PTPC bounce model (<code>PTPC_UHT_bounce.py</code>) and representative outputs used to generate the figures in the paper. The code integrates the coupled system of equations for the scale factor a(t)a(t)a(t), Hubble parameter H(t)H(t)H(t), tension field T(t)T(t)T(t), Ricci scalar R(t)R(t)R(t), entropy S(t)S(t)S(t), and tension energy density ρT\rho_TρT.Included files:Python source code (<code>PTPC_UHT_bounce.py</code>)Parameter sets for representative runs (α,β,Tcrit,V(T)\alpha, \beta, T_{\mathrm{crit}}, V(T)α,β,Tcrit,V(T))Output arrays of trajectories across multiple bouncesMulti-panel plots (PNG/PDF) for a(t)a(t)a(t), H(t)H(t)H(t), T(t)T(t)T(t), S(t)S(t)S(t), R(t)R(t)R(t), and ρT\rho_TρTThis dataset ensures full reproducibility of the PTPC simulations and provides a starting point for independent verification, parameter exploration, and future model extensions.License: CC BY 4.0.
本数据集配套论文《张力驱动势下的宇宙演化:统一形式体系》。
本数据集包含PTPC反弹模型(PTPC bounce model)的完整Python实现代码(文件名为`PTPC_UHT_bounce.py`),以及用于生成论文中各图表的典型输出结果。该代码实现了尺度因子$a(t)$、哈勃参数$H(t)$、张力场$T(t)$、里奇标量$R(t)$、熵$S(t)$以及张力能量密度$
ho_T$的耦合方程组的数值积分。
包含文件如下:
- Python源代码(`PTPC_UHT_bounce.py`)
- 典型模拟运行的参数集(包含$alpha$、$eta$、临界张力$T_{mathrm{crit}}$与势能$V(T)$)
- 多次反弹过程的轨迹输出数组
- 用于展示$a(t)$、$H(t)$、$T(t)$、$S(t)$、$R(t)$及$
ho_T$的多面板绘图文件(格式为PNG/PDF)
本数据集可保障PTPC模拟的完全可复现性,同时为独立验证、参数探索及后续模型拓展提供了基础支撑。
