Black holes as critical point of quantum phase transition
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 quan...
متن کاملQuantum electromagnetic “black holes” in a strong magnetic field
As demonstrated by Chernodub, strong magnetic field forces vacuum to develop real condensates of electrically charged ρ mesons, which form an anisotropic inhomogeneous superconducting state similar to Abrikosov vortex lattice. As far as electromagnetic field behaviour is concerned, this state of vacuum constitutes a hyperbolic metamaterial [1]. Here we demonstrate that spatial variations of mag...
متن کاملIntroduction to the AdS / CFT Correspondence
This is a thesis of the Quantum Fields and Fundamental Forces MSc at Imperial College London, introducing the ADS/CFT correspondence, focused on the duality between N = 4, d = 4 Superconformal Yang Miils theory and string theory on an AdS5×S background.
متن کاملThe Extreme Physics Explorer
Some tests of fundamental physics the equation of state at supra-nuclear densities, the metric in strong gravity, the effect of magnetic fields above the quantum critical value can only be measured using compact astrophysical objects: neutron stars and black holes. The Extreme Physics Explorer is a modest sized (∼500 kg) mission that would carry a high resolution (R ∼300) X-ray spectrometer and...
متن کاملStrings, black holes, and Lorentz contraction.
Consistency of quantum mechanics in black hole physics requires unusual Lorentz transformation properties of the size and shape of physical systems with momentum beyond the Planck scale. A simple parton model illustrates the kind of behavior which is needed. It is then shown that conventional fundamental string theory shares these features. ⋆ [email protected]
