WebTopological defects are the fundamental emergent excitations when a new ordered phase is formed by breaking a continuous symmetry ( 21, 22 ). They are singular points or lines in the otherwise spatially continuous configuration of the order-parameter field. WebDiverse topological defects arise in hexagonal manganites, such as ferroelectric vortices, as well as neutral and charged domain walls. The topological defects are intriguing … WebWhen 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. These show how some homotopy classes split into several distinct defects, while other homotopy classes do not occur physically. chicken bites recipes for dinner
