PhD project
Crosses and flowers:
Investigating superstructures in the high-Tc superconductor La2-xSrxCuO4+y
A PhD project in experimental condensed matter physics carried out at the Niels Bohr Institute, University of Copenhagen
This website contains the submitted version of the thesis, material related to the defence, selected figures and illustrations, and additional information about the experiments behind the project.
This was part of a so-called 4+4 PhD project, where I also did my master's within the same (longer) project period. There is a dedicated project page for the master's thesis, as well.

About the layout
I wrote the thesis using my own class (a modified LaTeX extbook class) using the Lucida font family. The class automatically generates a front page and front matter following the current University of Copenhagen specifications. Part and chapter headers are typeset in a similar manner, with a graphic box containing the part number (Roman numerals) or chapter number in the chosen KU colour.
Most illustrations in the thesis were created by me using PSTricks. Data analysis and visualization were carried out primarily in MATLAB and Python. A significant part of the project involved not only analysing data, but also developing figures and visualizations that could help understand and communicate the results.
