The cover picture of physica status solidi (b), taken from the Editor's Choice of this issue, shows a scheme of construction of the spin nematic ordered state and the topological interaction between spatially disconnected gauge defects. The gauge symmetry is broken by applying an external field B . The theory described in the paper [1] offers a potential explanation for recent observations of magnetic field induced antiferromagnetism in La 1.9 Sr 0.1 CuO 4 . The first author, Jan Zaanen, is Professor of Physics at the Instituut‐Lorentz in Leiden where he works on quantum field theory in condensed matter physics, concentrating on problems in high‐ T C superconductivity, quantum magnetism, quantum liquid crystals, doped Mott insulators, and strongly correlated electron systems. This paper is an invited presentation from the European Conference Physics of Magnetism (PM'02), held in Poznań, Poland, 1–5 July 2002. The proceedings of this conference are published in two parts: in the present issue of phys. stat. sol. (b) and in phys. stat. sol. (a) 196 , No. 1 (2003).
