Decay of Graviton Condensates and their Generalizations in Arbitrary
  Dimensions
  Classicalons are self-bound classical field configurations, which include
black holes in General Relativity. In quantum theory, they are described by
condensates of many soft quanta. In this work, their decay properties are
studied in arbitrary dimensions. It is found that generically the decays of
other classicalons are enhanced compared to pure graviton condensates, ie.
black holes. The evaporation of higher dimensional graviton condensates turns
out to match Hawking radiation solely due to non-linearites captured by the
classicalon picture. Although less stable than black holes, all self-bound
condensates are shown to be stable in the limit of large mass. Like for black
holes, the effective coupling always scales as the inverse of the number of
constituents, indicating that these systems are at critical points of quantum
phase transitions. Consequences for cosmology, astro- and collider physics are
briefly discussed.
