In order to refine the comparison between $\Psi^\mu$ and $\Psi^J$, we

From these data, one can clearly notice several trends.

First, from Table~\ref{tab:table_on_top}, we can observe that the overall

on-top pair density decreases when $\mu$ increases, which is expected

as the two-electron interaction increases in $H^\mu[n]$.

First, the overall on-top pair density decreases when $\mu$ increases,

which is expected as the two-electron interaction increases in

|

Second, Fig.~\ref{fig:densities} shows that the relative variations of the on-top pair density with respect to $\mu$
|
||||
are much more important than that of the one-body density, the latter
|

being essentially unchanged between $\mu=0$ and $\mu=\infty$ while the

former can vary by about 10$\%$ in some regions.

|

|

These data suggest that the wave functions $\Psi^{0.5 \le \mu \le 1}$ and $\Psi^J$ are close,
|
||||
and therefore that the operators that produced these wave functions (\ie, $H^\mu[n]$ and $e^{-J}He^J$) contain similar physics.
