#+title: Configuration Sigma Vector Helpers
#+author: Vijay Gopal Chilkuri

* Generate the singly excited configurations on-the-fly
The algorithm is based on the work by Garniron et. al. (see thesis Chap 5).
The basic idea is to generate \(|\alpha\rangle\)'s on-the-fly.
The algorithm is based on the idea of splitting the list of \(|\alpha\rangle\)'s
into blocks associated with a selected determinant \(|D_I\rangle\).
** Create a function to return a list of alphas
Here we create a list of \(|\alpha\rangle\)'s associated with
the input determinant \(|D_I\rangle\).
