Analytical theory for dark soliton interaction in nonlocal nonlinear materials with arbitrary degree of nonlocality
arXiv:1005.4971 · doi:10.1103/PhysRevA.82.013826
Abstract
We investigate theoretically the interaction of dark solitons in materials with a spatially nonlocal nonlinearity. In particular we do this analytically and for arbitrary degree of nonlocality. We employ the variational technique to show that nonlocality induces an attractive force in the otherwise repulsive soliton interaction.
