Figures

Below are all my illustrations and data plots that I've made for the thesis. In the caption for each, there are download links both to 900 dpi PNG images (and for some figures also an αPNG with transparent background), vector formats (SVG and PDF), and any alternative versions of the figures. Note also that some figures have full-vector versions in SVG and PDF - these files contain the full data sets and are very heavy.

Most of the illustrations are created entirely in LaTeX using PSTricks, while most of the data plots were made in either MATLAB or using Python. Some of them were originally made for my master's thesis, though most have been updated for the PhD thesis.

Superconductivity timeline figure

The superconductivity timeline figure (Fig. 2.2 above) was originally made for my master's thesis, and I put it on Wikimedia Commons to replace an old figure that was out of date. The figure became pretty popular, ending up in lots of publications, including a few books (on the front page of one of them, even), and used in countless slideshows. The version in the PhD thesis is fully up to date, and has - as of June 2026 - been placed as the newest version on Wikimedia Commons as well. Here, I show the figure in a few different versions, including download links in whatever format you might prefer, if you want to use it.

Note that these figures all use the color scheme used in the original Wikimedia Commons figure, unlike the Fig. 2.2 above - which instead use the PhD thesis color scheme.

Let me know if you need a different kind of version of the figure. For example, I have previously made Danish translations of the figure, and figure versions with greyscale or two-toned instead of more colors.

The standard figure: Items that need pressures are simply marked with an asterisk, and the figure has a white background inside the axes.
