Web1 jul. 1999 · Topological defects are ubiquitous in physics. Whenever a symmetry breaking phase transition occurs, topological defects may form. The best known examples are vortex lines in type II super conductors or in liquid helium, and declination lines in liquid crystals ( Mermin, 1979; Chuang et al., 1991 ). ourdaily tabletWebWhen translational symmetry is broken in the ground state, the homotopy theory of defects of ordered media has to be supplemented with integrability conditions, coming from the theory of foliations.
