    "abstract": "We demonstrate a break-down in the macroscopic (classical-like) dynamics of\nwave-packets in complex microscopic and mesoscopic collisions. This break-down\nmanifests itself in coherent superpositions of the rotating clockwise and\nanticlockwise wave-packets in the regime of strongly overlapping many-body\nresonances of the highly-excited intermediate complex. These superpositions\ninvolve $\\sim 10^4$ many-body configurations so that their internal interactive\ncomplexity dramatically exceeds all of those previously discussed and\nexperimentally realized. The interference fringes persist over a time-interval\nmuch longer than the energy relaxation-redistribution time due to the\nanomalously slow phase randomization (dephasing). Experimental verification of\nthe effect is proposed.",
