\section{Introduction}
You can use bibtex for references. Single reference is cited as follows \cite{chiaverini2005surface}, and set of references as follows \cite{leibfried2005surface,seidelin2006microfabricated,daniilidis2011fabrication}. Please include the DOI of each reference if it is available.

\section{Mathematical and scientific notation}
\subsection{Displayed equations} Displayed equations should be centered.
Equation numbers should appear at the right-hand margin, in
parentheses:
\begin{equation}
J(\rho) =
\frac{\gamma^2}{2} \; \sum_{k({\rm even}) = -\infty}^{\infty}
\frac{(1 + k \tau)}{ \left[ (1 + k \tau)^2 + (\gamma \rho)^2 \right]^{3/2} }.
\label{niceEq}
\end{equation}
All equations should be numbered in the order in which they appear
and should be referenced from within the main text as Eq. (\ref{niceEq}),
Eq. (\ref{LaplaceElectrostaticEquation}). We suggest to use align command for set of equations.
The mathematical problem requires to solve a Laplace's equation for the scalar electric potential $\Phi(\boldsymbol{r})$ given by
\begin{align}
\nabla^2 \Phi(\boldsymbol{r}) =& 0, &&\boldsymbol{r} \in \mathfrak{D}=\left\{\boldsymbol{r} \in \mathbb{R}^3 : z > 0 \right\}, \label{LaplaceElectrostaticEquation}
\end{align}{}
subjected to the following Dirichlet and Neumann boundary conditions:
\begin{align}
\Phi(\boldsymbol{r}) &= V_o \hspace{0.5cm} &&\mbox{\textbf{if}} \hspace{0.5cm} \boldsymbol{r} \in \mathcal{A}_{in} \subset \left\{\boldsymbol{r} \in \mathbb{R}^2 : z = 0 \right\},\label{DirichletBoundaryConditionsEq1}\\
\Phi(\boldsymbol{r}) &= 0 \hspace{0.5cm} &&\mbox{\textbf{if}} \hspace{0.5cm} \boldsymbol{r} \in \left\{\boldsymbol{r} \in \mathbb{R}^2 : z = 0 \right\}\setminus\mathcal{A}_{in}\cup\mathcal{G},
\label{DirichletBoundaryConditionsEq2}\\
\frac{\partial \Phi(\boldsymbol{r})}{\partial z} &=0 &&\mbox{\textbf{if}} \hspace{0.5cm} \boldsymbol{r} \in \mathcal{G}.
\label{NeumannBoundaryConditionsEq}
\end{align}
