where $\chi$ is a Gaussian random variable, and the potential term
can be simulated by creating or destroying particles over time (a
so-called branching process) or by simply considering it as a
cumulative multiplicative weight along the diffusion trajectory.
cumulative multiplicative weight along the diffusion trajectory:
\[
\exp \left( \int_0^\tau - (E_L(\mathbf{r}_t) - E_{\text{ref}}) dt \right)
\]
We note that the ground-state wave function of a Fermionic system is
