Black holes as critical point of quantum phase transition
See More ...
We reformulate the quantum black hole portrait in the language of modern
condensed matter physics. We show that black holes can be understood as a
graviton Bose-Einstein condensate at the critical point of a quantum phase
transition, identical to what has been observed in systems of cold atoms. The
Bogoliubov modes that become degenerate and nearly gapless at this point are
the holographic quantum degrees of freedom responsible for the black hole
entropy and the information storage. They have no (semi)classical counterparts
and become inaccessible in this limit. These findings indicate a deep
connection between the seemingly remote systems and suggest a new quantum
foundation of holography. They also open an intriguing possibility of
simulating black hole information processing in table-top labs.
