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.
Projection of the Fermi surface of LaPtAl4Si2 along the c-axis.
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.
