2024.10 更新

注意，如果你显示所有公式是错误的，请刷新一下页面，至少对于我的谷歌浏览器来说刷新一下就好了

更换主题后原来那种方法不太适用了，而且 mathjax 渲染不太好看，目前我更改为 KaTeX 渲染，以某一篇要渲染公式的markdown为例子:

示范, 行内公式 `$ ... $`: $G(t) = \langle S(t)S(0)\rangle$

行间公式 `$$ ... $$` ...

不过本来最理想的效果就这么显示了，但我发现最后还是要相当于这样：

1
2
3
4
5
<span>
$$
G(t) = \langle S(t)S(0)\rangle
$$
</span>
$$ G(t) = \langle S(t)S(0)\rangle $$

才可以渲染出来

在themes里配置好 mathjax 的环境之后，最好在 博客.md 的顶部追加：

mathjax: true

现在无论是居中公式:

$$
-\ln \langle \frac{g(t_m)}{g(t_i)} \rangle_{\text{each rank}} \
$$

$$
\sum_{\text{rank 0}}^{50} -\ln \langle \frac{g(t_m)}{g(t_i)} \rangle = -\ln \langle \frac{g(t_m)}{g(t_i)} \rangle_{\text{each bin}}
$$

Finally, we will get 10 bin data.

ZJR old MPI:
$$
\text{each rank } \prod_t \langle \frac{g(t+\delta)}{g(t)} \rangle \ \ -\text{enrg1} \
\text{all rank } \prod_r \langle \frac{g(t+\delta)}{g(t)} \rangle
$$

Benchmark from…

还是行内公式 都可以正常识别了.

Two dimensional $L\times L/2$ Heisenberg model, region A is chosen to be $L/2 \times L/2$ without corners. The temperatures are chosen to be $1/T = L$.

The fitting result is:
$$
\color{yellow }{S^2(A) = 0.092 L + 1.00\ln L -1.63}
$$
gives ==2.6145== for $8 \times 16$ Lattice and ==1.18544== for $4 \times 8$ Lattice.
