Frustrated Brownian Motion of Nonlocal Solitary Waves
Frustrated Brownian Motion of Nonlocal Solitary Waves
We investigate the evolution of solitary waves in a nonlocal medium in the presence of disorder. By using a perturbational approach, we show that an increasing degree of nonlocality may largely hamper the Brownian motion of self-trapped wave-packets. The result is valid for any kind of nonlocality and in the …
