\begin{equation}

\vec{\mathrm{v}}(t) \mathrm{\vec{v}}(t) \rightarrow
\vec{\mathrm{V}} \mathrm{\vec{V}} =
(1-\alpha)\vec{\mathrm{v}}(t) (1-\alpha)\mathrm{\vec{v}}(t) + \alpha
|\vec{\mathrm{v}}(t)|\hat{F}(t)\ |\mathrm\vec{{v}}(t)|\hat{F}(t)\ ,

where
$\vec{\mathrm{v}}$ $\mathrm{\vec{v}}$ is the velocity of the atoms, $\alpha$ is an adaptative parameter, and $\hat{F}$ is an unitary vector in the direction of the force $\vec{F}$. By doing this velocity modification, the acceleration of the atoms are given by
