MQDT

MQDT.jl is a Julia package designed to calculate Rydberg states and matrix elements using multi-channel quantum defect theory (MQDT).

Installing Julia

curl -fsSL https://install.julialang.org | sh

Update the package dependencies

julia --project=. -e 'using Pkg; Pkg.resolve(); Pkg.instantiate()'

Running tests

julia --project=. -e 'using Pkg; Pkg.test()'

Building docs

From within the docs directory, you can build the documentation with:

julia --project=. -e 'import Pkg; Pkg.develop(path=".."); Pkg.instantiate(); include("make.jl")'

This will also automatically run the doctests in the documentation.

Running examples

From within the examples directory, first initialize a new julia project and install the MQDT.jl package in development mode:

julia --project=. -e 'import Pkg; Pkg.develop(path=".."); Pkg.instantiate()'

Then you can run a script (from within the examples directory) like this:

julia --project=. generate_lu_fano.jl
