文摘

We obtain an analytical vector Hermite鈥揋aussian spatial soliton solution of the (2+1)-dimensional coupled nonlocal nonlinear Schr枚dinger equation in the inhomogeneous nonlocal nonlinear media, and investigate the periodic expansion and compression behaviors of Hermite鈥揋aussian spatial solitons in a periodic modulation system. The structure of Hermite鈥揋aussian soliton lattice is decided by the degree (n, m) of Hermite polynomials. The evolution of the soliton-lattice breather appears the full breathing cycle, and the interval between solitons oscillates periodically as the wave propagates. The amplitude and width change periodically; however, they exist opposite trend in the periodic modulation system.
