Christmas image of the week: Fermi surfaces

To get us in the festive spirit we have been keeping an eye out for images that remind us of Christmas. In the first Christmas Image of the Week I look at strongly correlated electrons in intermetallic compounds and why they exhibit a wide variety of properties from heavy fermion behaviour to quantum criticality and unconventional superconductivity.

In this paper by N J Ghimire et al the authors explore the physical properties of these fascinating tetragonal cerium-based compounds. In the image above you can see a projection of the Fermi surface of the respective compounds studied in the paper along the c-axis, although here at JPhys+ we thought it kind of looked like a snowflake.
