The position of the Scotch egg in modern physics


This study was one of the first to explicitly introduce the concept of the “Scotch egg” into modern physics research. Scotch eggs are a foodstuff of sorts (with a history that is in some dispute). The study:

The crystal structures of the elements: pseudopotential theory revisited,” J Hafner and Volker Heine [pictured here], Journal of Physics F: Metal Physics, 1983, Vol.13(12), pp. 2479-2501. The authors, at Technische Universitat Wien, Austria and the University of Cambridge, UK, report:

“…we find that the relation [defined in this paper] holds fairly well over a wide range of electron densities. Incidentally, this substantiates the ‘scotch-egg’ model of HW [Volker Heine and D. Weaire]…  At constant Rc, and variable Rs, the repulsive core expands with Rs1/2 (equation (2.4)) while Rmin remains constant-the core moves over the attractive wiggle with decreasing electron density (increasing screening length). This is just the ‘scotch-egg’ behaviour.”

Here’s detail from the study:
