\begin{block}{Abstract}
Wave equations with energy-dependent potentials are well known in physics. They appear both in relativistic and non-relativistic quantum mechanics, also were used largely in particle, nuclear and atomic physics. More recently, a great interest has been brought to this type of potentials in non-relativistic quantum mechanics. Their presence in the Schrödinger wave equation generates a reformulation of the probability density to ensure the conservation of the continuity equation. The energy levels of nuclei provide an idea of their nuclear structure. Therefore, all the nuclear models, which have evolved from 1930s to now, are expected to reproduce the energy levels. One of the fundamental models of nuclear structure is the cluster
model. In the present work, we propose to calculate analytically the ground state energies of some nuclei using an energy-dependent potential in the cluster model. With a suitable parameters values, we compare the obtained results with the available experimental data.%
\end{block}
\begin{block}{The energy-dependent potentials}
In this section, we present the quantum supersymmetry, in 3 dimensional
space, extended to the case where the potentials are energy-dependent
\cite{yekken2013applying}. Starting from the generalization of the
superpotential in order to factorize the Hamiltonian $H_{n}$. Here
we have considered this notation to indicate the energy-dependence
of the Hamiltonian ($\hbar=m=e=1$)
\begin{equation}
H_{n}=-\frac{1}{2}\nabla^{2}+V_{n}(\boldsymbol{r},E_{n}),\ \ \ n=0,1,2...,
\end{equation}
where $n$ is the radial quantum number which represents the nodes
number.
Details concerning the modifications of the usual rules of quantum
mechanics required by the energy-dependence of the potential can be
found in \cite{lombard2007wave,formanek2004wave,yekken2010energy}
(and references therein). We recall that the constraint imposed by
the continuity equation requires the density distribution to be defined
by \cite{formanek2004wave}
\begin{equation}
\rho(\boldsymbol{r},E_{n})=\psi_{n}^{*}(\boldsymbol{r},E_{n})\left[1-\frac{\partial V_{n}(\boldsymbol{r},E_{n})}{\partial E_{n}}\right]\psi_{n}(\boldsymbol{r},E_{n}).
\end{equation}
It is to note that the probability density has to be positive definite
and this is ensured if and only if
\begin{equation}
1-\frac{\partial V_{n}(\boldsymbol{r},E_{n})}{\partial E_{n}}>0.\label{eq:positivity-condition}
\end{equation}
Accordingly, the scalar product is written as
\begin{equation}
\left(\psi_{n}\right|\left.\psi_{n}\right\rangle =\int\psi_{n}^{*}(\boldsymbol{r},E_{n})\left(1-\frac{\partial V_{n}(\boldsymbol{r},E_{n})}{\partial E_{n}}\right)\psi_{n}(\boldsymbol{r},E_{n})d\boldsymbol{r}.
\end{equation}
The notation $\left(\psi_{n}\right|\left.\psi_{n}\right\rangle $
is used instead of $\left\langle \psi_{n}\right|\left.\psi_{n}\right\rangle $
to distinguish the difference between the two scalar products.

@Comment{jabref-meta: databaseType:biblatex;}
正如您在图中所看到的，参考文献左侧没有数字。
答案1
这
\setbeamertemplate{bibliography item}{\scalebox{1.5}{\pgfuseimage{beamericonarticle}}}
明确utfprpgtex-poster.sty禁用参考书目中的编号并强制显示小图标（虽然公平地说，放置小图标已经是投影仪的默认设置，这一行并没有让事情变得更糟，它只是稍微缩放了图标）。如何获取 Beamer 书目中的编号条目解释说你可以使用以下方法取回引用标签
\setbeamertemplate{bibliography item}{\insertbiblabel}
不幸的是，仅此一点是行不通的，因为utfprpgtex-poster.sty它还以一种与数字样式基本不兼容的方式重新定义了书目环境。定义如下
\defbibenvironment{bibliography}{%
\list{\printfield[labelalphawidth]{labelalpha}}{%
% \setlength{\labelwidth}{\labelalphawidth}%
\setlength{\leftmargin}{\labelwidth}%
\setlength{\labelsep}{\biblabelsep}%
\addtolength{\leftmargin}{\labelsep}%
\setlength{\itemsep}{\bibitemsep}%
\setlength{\parsep}{\bibparsep}%
}%
\renewcommand*{\makelabel}[1]{\hss##1}%
}{\endlist}{\item}
并且只适用于aphabetic样式（但比较正确的定义alphabetic.bbx，字段labelprefix和extraalpha也应该打印；因此，即使对于字母样式，定义也是有缺陷的）。您想完全摆脱这块代码。
如果直接修改.sty文件，请改名并在修改后的文件的顶部放置更改的简短通知以及适当的版本和日期信息。未重命名文件的情况下，请勿更改.sty文件。
如果你不想改变，.sty你可以通过添加覆盖文档序言中不需要的代码
\setbeamertemplate{bibliography item}{\insertbiblabel}
以及数字样式的正确书目定义
\defbibenvironment{bibliography}
{\list
{\printtext[labelnumberwidth]{%
\printfield{labelprefix}%
\printfield{labelnumber}}}
{\setlength{\labelwidth}{\labelnumberwidth}%
\setlength{\leftmargin}{\labelwidth}%
\setlength{\labelsep}{\biblabelsep}%
\addtolength{\leftmargin}{\labelsep}%
\setlength{\itemsep}{\bibitemsep}%
\setlength{\parsep}{\bibparsep}}%
\renewcommand*{\makelabel}[1]{\hss##1}}
{\endlist}
{\item}
必须再次添加参考书目环境有点不幸，但.sty已经覆盖了正确的定义。
总体而言，我建议不要使用在 Overleaf 上找到的随机模板。你永远无法确定它们是否可以更改以满足你的需求，而且它们通常得不到适当的维护或支持。
