Webthis critical behavior, known as the Lifshitz point. The modulated phase possesses a fixed equilibrium wavevector which vanishes continuously as the Lifshitz point is approached. When the components of this wavevector span an m-dimensional subspace, the system under consideration displays an m-fold Lifshitz critical behavior.
