There are an unusually large number of correlated‐electron superconductors with a carrier concentration per site of 1 / 2 . Precisely at this carrier concentration, there is a strong tendency to form local spin‐singlets. On page 1053 (DOI: 10.1002/qua.24637 ), Sumitendra Mazumdar and Rudolf Torsten Clay propose that superconductivity is due to the condensation of mobile spin‐singlets at a larger frustration. The cover shows the crystal structure of κ‐BEDT‐TTF compounds, within the layer containing these organic molecules. The crystal consists of dimers of molecules, rotated at 90° relative to the nearest neighboring dimers.
