    "abstract": "We demonstrate a dramatic change in the interaction forces between dark\nsolitons in nonlocal nonlinear media. We present what we believe is the first\nexperimental evidence of attraction of dark solitons. Our results indicate that\nattraction should be observable in other nonlocal systems, such as\nBose-Einstein condensates with repulsive long-range interparticle interaction.",
