Quantum vortices of strongly interacting photons

Experimental data: We use a .csv file format for all data sets. File names follow the figure numbers in the main text, and each figure is associated with separate x-axis and y-axis files. Matlab .fig and .svg files are also included for all figures. fig_2.zip consists of the data for Figure 2A-C and the corresponding x-axis and y-axis vectors in separate files. fig_3.zip consists of the phi^3 data files and the corresponding x-axis and y-axis vectors for figures 3A-D. For fig_3D, the data needs to be reshaped with [length(yaxis_3D), length(xaxis_3D), length(zaxis_3D)]) to get the correct dimensions. fig_4.zip consists of the g^3 data files and the corresponding x-axis and y-axis vectors for figures 4A-F. Simulation: fig_2_full_simulation.nb is a Mathematica code of the simulation generating the results in Fig. 2C-E.
