• Title: Evaporating black holes and late-stage loss of soft hair
• Authors: Peng Cheng
• Abstract summary: We present a paradox for evaporating black holes, which is common in most schemes trying to avoid the firewall by decoupling early and late radiation. At the late stage of the black hole evaporation, the decoupling between early and late radiation can not be realized because the black hole has a very small coarse-grained entropy. We call the problem hair-loss paradox as a pun on losing black hole soft hair during the black hole evaporation and the situation that the information paradox has put so much pressure on researchers.

• Abstract: We present a paradox for evaporating black holes, which is common in most schemes trying to avoid the firewall by decoupling early and late radiation. At the late stage of the black hole evaporation, the decoupling between early and late radiation can not be realized because the black hole has a very small coarse-grained entropy, then we are faced with the firewall again. We call the problem hair-loss paradox as a pun on losing black hole soft hair during the black hole evaporation and the situation that the information paradox has put so much pressure on researchers.

• Black Hole Firewalls and Quantum Mechanics [0.0]
  Firewalls in black holes are easiest to understand by imposing time reversal invariance, together with a unitary evolution law. Our conclusion contradicts other findings, particularly a recent paper by Strauss and Whiting. Indeed, the firewall transformation removes the entanglement between very early and very late in- and out-particles, in a far-from-trivial way.

  Accelerating relativistic mirror has long been recognized as a viable setting where the physics mimics that of black hole Hawking radiation. Chen and Mourou proposed a novel method to realize such a system by traversing an ultra-intense laser through a plasma target with a decreasing density. An international AnaBHEL Collaboration has been formed with the objectives of observing the analog Hawking radiation and shedding light on the information loss paradox.

• A dialog on the fate of information in black hole evaporation [77.34726150561087]
  We present two alternative perspectives for the resolution of Hawking's information puzzle in black hole evaporation. One of them is the central role played by the existence of the interior singularity that we expect to be replaced by a more fundamental quantum gravity formulation. Both views rely on the notion that the standard effective quantum field theoretic perspective would require some deep modifications.

The quantum walks of quasi-particle in the curved spacetime reflect the gravitational effect near the black hole, resulting in the behaviour of stimulated Hawking radiation.

  We consider a version of the Hayden-Preskill thought experiment in which the message thrown into the black hole is itself a smaller black hole. We then discuss the implications of the existence of a recovery channel for this black hole message at infinity. We suggest decoherence mechanisms as a way of resolving this sharpened paradox.
