In recent years, the existence of solutions with finite energy ( bound states ) of the stationary
nonlinear Schrödinger equation has been extensively investigated, such equations are related with different phisycs models, for example plasms physics, they are related with the existence of standing waves of the nonlinear Schrödinger equation (NLS), mainly in the semiclassical. In that work, basead in Alves, Figueiredo and Furtado (2009) and motivated by the results and methods developed by Del Pino and Felmer (1996), of the scalar equation, it is developed a penalization method for the energy functional associated to a type gradient systems. We study the existence, multiplicity and concentration of positive solutions for system and obtain results analogous to that of the scalar equation. The main tools used are Variational methods, Moutain pass theorem, Lusternik-Schnirelman of category, Penalization methods , Maximum Principle properties of Sobolev spaces.
