Descripción: Abstract: Black holes are considered exceptional due to their time evolution and information processing. However, it was proposed recently that these properties are generic for objects, the so-called saturons, that attain the maximal entropy permitted by unitarity. The present paper verifies this connection within a renormalizable SU(N) invariant theory. We show that the spectrum of the theory contains a tower of bubbles representing bound states of SU(N) Goldstones. Despite the absence of gravity, a saturated bound state exhibits a striking correspondence with a black hole: Its entropy is given by the Bekenstein-Hawking formula; semiclassically, the bubble evaporates at a thermal rate with a temperature equal to its inverse radius; the information retrieval time is equal to Page’s time. The correspondence goes through a trans-theoretic entity of the Poincaré Goldstone. The black hole–saturon correspondence has important implications for black hole physics, both fundamental and observational.
