Explanations of structure for data files
========================================

Files included in the zip file:
(1) c6multichannelcontributions.csv
(2) c6multichannelcontributionstriplet.csv
(3) nonperturbative6channeln30.csv
(4) potentialcurves4levels.csv
(5) potentialcurves4levelsmicrowave.csv
(6) spinchains4levelsangmom.csv
(7) spinchains4levelsspin.csv
(8) spinchains4levelsangmommicrowaves.csv
(9) spinchains4levelsspinmicrowaves.csv

====================================================================================================
c6multichannelcontributions.csv and c6multichannelcontributionstriplet.csv
==========================================================================
These files contain the singlet-singlet, singlet-triplet, triplet-singlet and triplet-triplet
contributions for the C6 coefficients of the 5snd 1D2 (file 1) and 3D2 (file 2) series of Sr,
for varying principal quantum numbers, n. The C6s assume the two atoms are initially in the
same state, and also that they are in the stretched state (J=|M_J|).

The columns are: n, singlet-singlet, singlet-triplet, triplet-singlet and triplet-triplet contributions.

====================================================================================================
nonperturbative6channeln30.csv, potentialcurves4levels.csv and potentialcurves4levelsmicrowave.csv
===================================================================================================
These three files contain the outputted potential curves shown in the paper. File 3 has the full
non-perturbative calculation for 2 atoms, file 4 has the non-perturbative calculations for the 
4 levels that contribute most (see paper for details), and file 5 has the same as file 4 but with the
microwave field applied, giving a shift of 200 MHz.

The columns in the files denote R (or a), and the value of the eigenvalue of the Hamiltonian.

====================================================================================================
spinchains4levelsangmom.csv and spinchains4levelsspin.csv
=========================================================
These two files contain the values of the average values of the angular momentum and spin quantum
numbers (J and S), respectively.

The values in the columns denote the values of a, t, J or S for atoms1, 2, 3 and 4 in the chain.

====================================================================================================
spinchains4levelsangmommicrowaves.csv and spinchains4levelsspinmicrowaves.csv
=============================================================================
Similarly to files 6 and 7, files 8 and 9 contain the average values for the quantum numbers J and S
respectively, but for varying values of the light shift induced by a microwave field.

The values in the columns denote the values of the microwave field shift, t, J or S for atoms1, 2, 3 and 4 in the chain.
