“…Recently, a field-theoretic renormalization group method for describing the unconventional critical behavior of some real imperfect systems known as manganites [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] was proposed [21]. These systems are complex and present a large number of strong interacting particles, defects, impurities, inhomogeneities, nonlinearities, competition etc.…”
