Black Hole Formation in Fuzzy Sphere Collapse

Understand

We study the collapse of a fuzzy sphere, that is a spherical membrane built out of D0-branes, in the BFSS model.

• At weak coupling, as the sphere shrinks, open strings are produced.
• If the initial radius is large then open string production is not important and the sphere behaves classically.
• At intermediate initial radius the back-reaction from open string production is important but the fuzzy sphere retains its identity.
