Abstract
A nonlinear model of the scalar field with a coupling between the field and its gradient is developed. It is shown, that such model is suitable for the description of phase transitions accompanied by formation of spatially inhomogeneous distributions of the order parameter. The proposed model is analogous to the mechanical nonlinear oscillator with the coordinate-dependent mass or velocity-dependent elastic module. Besides, for some values of energy the model under consideration has exact analytical solution. This model may be related to the spinodal decomposition, quark confinement, or cosmological scenario. All predictions can be verified experimentally.
