双倍距离 tikz 没有效果（beamer 演示）

这是我的框架：

\begin{frame}
\frametitle{Reactant distribution \\and finite Larmor radius effect}
\begin{columns}
\begin{column}{0.5\textwidth}
\begin{itemize}
\item changes in $\mathbf{k_p}$ affect the \textbf{cut-off energy} of the\tikz\node [coordinate] (n1) {}; reactant energy distribution
\item \textbf{only} the \textbf{upward} gyro-\tikz\node [coordinate] (n2) {};motion is seen by the detector 
\end{itemize}
\begin{figure}
\vspace{-0.3cm}
\centering
\tikz{\node [anchor=base] (t3) 
{\includegraphics[height=0.45\textheight]{pics/totspectrum.png}};
}
\end{figure}
\end{column}
\begin{column}[t]{0.5\textwidth}
\begin{figure}
\vspace{-5.4cm}
\centering
\tikz{\node [anchor=base] (t1) {\includegraphics[height=0.5\textheight]{pics/distro_kp.png}};}
\end{figure}
\begin{figure}
\centering
\vspace{-1.1cm}
\tikz{\node [anchor=base] (t2) {\includegraphics[height=0.5\textheight]{pics/orbit.png}};}
\end{figure}
\end{column}
\end{columns}
\begin{tikzpicture}[overlay]
        \path[->]<1-> (n1) edge [color=orange, out=0, in=180] (t1);
        \path[->]<1-> (n2) edge [color=orange, out=-30, in=150] (t2);
        \path[thin,double distance=5pt,->] <1-> (t2) edge [out=180,in=0](t3);
\end{tikzpicture}
\end{frame}

问题在于 (t2) 和 (t3) 之间的箭头。我想要一个双线箭头，线条之间有可见的距离。它应该有“暗示”的含义。我尝试多次更改双倍距离的值，但没有任何变化：我看到的总是一个非常细的箭头，我看不出它是双箭头。你能帮帮我吗？谢谢大家。

使用\tikzmark并定义边缘为

every edge/.append style = {very thick, -{Triangle[angle=60:1pt 3]}}

你可以画双线

    \path   (pic cs:g2) edge [semithick, double distance=3pt, 
                              out=180,in=345] (pic cs:g3);

添加缺失代码后使用\tikzmarks 可得到以下结果：
