“…Nonlinearity has generated crucial effects and phenomena not only in the macroscopical systems but also in the microscopical systems governed by quantum physics. We can cite as examples Rogue waves [10][11][12], bifurcation [13,14], bistability [15][16][17][18], chaos [19][20][21][22], phase transition [23][24][25][26], lasing [27][28][29][30][31], superradiance [32][33][34], correlations [35][36][37], squeezing [38][39][40][41], and solitons [42][43][44][45][46][47][48]. A particular interest is focused on solitons due to their potential new application perspectives in several fields of physics and engineering [49][50][51][52][53][54][55][56].…”
