Quantum Black Holes and Thermalization in Relativistic Heavy Ion Collsions
A new thermalization scenario for heavy ion collisions is discussed. It is based on the Hawking–Unruh effect: an observer moving with an acceleration a experiences the influence of a thermal bath with an effective temperature T = a/2π, similar to the one present in the vicinity of a black hole horizon. In the case of heavy ion collisions, the acceleration is caused by a pulse of chromo–electric...
متن کاملBlack Holes and Relativistic Jets
There is strong observational evidence that AGN, Galactic X-ray transients and (probably) γ-ray bursts are associated with black holes, and that these sources are able to form collimated, ultrarelativistic outflows. There is much interest in trying to understand how these prime movers are able to release energy from accreting gas and their own spin energy. Electromagnetic field plays a large ro...
متن کاملThe Schwinger Mechanism, the Unruh Effect and the Production of Accelerated Black Holes
We prove that the Heisenberg-Euler-Schwinger mechanism –pair creation in a constant electric field– and its radiative corrections imply the Unruh effect, i.e. the thermalisation of accelerated systems at temperature a/2π where a is the acceleration. More precisely, the properties of the amplitudes for pair creation under crossing symmetry and CPT are sufficient to deduce the Unruh effect. Furth...
متن کاملSpin and Relativistic Phenomena Around Black Holes
Ever since the seminal work of Penrose (1969) and Blandford & Znajek (1977), it has been realized that black hole spin may be an important energy source in astrophysics. X-ray observations are uniquely able to answer: Does black hole spin play a crucial role in powering relativistic jets such as those seen from radio-loud active galactic nuclei (AGN), Galactic microquasars, and Gamma-Ray Bursts...
متن کاملQuantum criticality and black holes.
Many condensed matter experiments explore the finite temperature dynamics of systems near quantum critical points. Often, there are no well-defined quasiparticle excitations, and so quantum kinetic equations do not describe the transport properties completely. The theory shows that the transport coefficients are not proportional to a mean free scattering time (as is the case in the Boltzmann th...
