The electric field following from $\vstat$ defined in \cref{eq:V_stat} is given by \begin{align} \estatc{x} &= -\frac{\partial \vstat}{\partial x} = \frac{V_0}{d^2} x, \\ \estatc{y} &= -\frac{\partial \vstat}{\partial y} = \frac{V_0}{d^2} y, \\ \estatc{z} &= -\frac{\partial \vstat}{\partial z} = -\frac{2 V_0}{d^2} z, \end{align} for all $|\vec r| < d$ and zero otherwise. The electric field following from $\vdyn$ is simply \begin{equation} \edyn = (1 + f \cos \omega_V t) \cdot \estat. \end{equation} \section{Special Case Analytical Solution} \label{app:special_case_analytical_solution} In the special case of a single particle in the potential $\vstat$, with the inital conditions $\vec{r}(t_0) = (x_0, 0, z_0)$ and $\vec{v}(t_0) = (0, v_0, 0)$, we can derive an analytical solution for the trajectory. The solution for the $z$ component is straightforward \begin{equation} z(t) = z_0 \cos(\omega_z t). \end{equation} From the equation system \begin{align} f(0) = A_+ e^{-i \phi_+} + A_- e^{-i \phi_-} &\equiv x_0, \\ \dot f(0) = -i \omega_+ A_+ e^{-i \phi_+} - i \omega_- A_- e^{-i \phi_-} &\equiv i v_0, \end{align} we derive $\phi_\pm = 0$ as $f(0) \in \mathbb{R}$ and therefore $A_+ + A_- = x_0$ and $\omega_+ A_+ + \omega_- A_- = -v_0$. Solving this system of equations for $A_\pm$ we find \begin{equation} A_\pm =\pm \frac{v_0 + \omega_\mp x_0}{\omega_- - \omega_+}. \end{equation} % =========================================== \onecolumngrid % \bibliographystyle{apalike} \bibliographystyle{unsrt} \bibliography{ref} \end{document}
