Clarify summing notation and fix error in derivation of Laplacian #3

Closed Schoyen closed 5 years ago

Schoyen commented 5 years ago

There has been some questions about common indices occurring in terms containing both products and sums, and whether or not these are "connected". I took the liberty of relabelling indices that are repeated, but which are not summed or multiplied together. An extra pair of eyes to check that this looks okay, would be perfect! Furthermore, there was a missing factor two in the cross term of the Laplacian of the full wave function with the Jastrow factor.

The two first commits of this pull request are concerned with the optional Project 2. This project is not yet completed.
