The nonlinear propagation of two-dimensional and three-dimensional terahertz electromagnetic beams in paralelectrics like SrTiO 3 is theoretically investigated in the temperature range T= 50 - 200 K. These beams are subject to the modulation instability that results in the formation of the sequence...
