Non-spherical collapse in AdS and Early Thermalization in RHIC    [PDF]

Enseok Oh, Sang-Jin Sin

In the flat space, it is well known that non-spherical shell collapses to give globular cluster after many oscillations. However, we show that in anti de sitter space, arbitrary shape of shell or cloud falls to form a black hole in one dynamical time. By gague/gravity dualuty, this explains the early thermalization in strong quark-gluon plasma. This is traced back to the a remarkable property of AdS : the amplitude independence of the period in radial motion in spite of the NON-linearity of the equation of motion. We investigated the interaction effect numerically and we did not observe any qualitative change in the behavior if the interaction is attractive.
