A new neural quantum state ansatz for bosons in the grand canonical ensemble achieves competitive variational energies in 1D and 2D systems and provides access to one-body reduced density matrices.
This factor is defined as a smoothed rectangular pulse that decays 13 exponentially outside a central window: qn = 1 1 + e−s(n−c1) · 1 1 + es(n−c2) , 0 ≤ c1 ≤ c2, s > 0
