Getting started

Julia package to compute entries of the irreducible representations of the unitary group (D-functions or group functions). It supports both numerical and symbolical group functions.

Documentation

Installation

Julia is already installed

Alternatively, you can install the package directly from the repository:

user@machine:~$ mkdir new_code 
user@machine:~$ cd new_code
user@machine:~$ julia --project=.
julia> # here you need to press the character `]`; the prompt turns blue
pkg > add https://github.com/davidamaro/GroupFunctions.jl

Getting Julia

• Mac: Use juliaup. Installing Julia via brew is not recommended.
• Linux: Use the appropriate package manager (e.g., sudo pacman -S julia).
• Windows: Run winget install julia -s msstore in your terminal and follow the steps.

Computing a single group function (symbolical)

my_fav_irrep = [2, 1, 0]
my_fav_basis = basis_states(my_fav_irrep)
output = group_function(my_fav_irrep, my_fav_basis[1], my_fav_basis[3])
julia_to_mma(output)
