# Black hole evaporation: information loss but no paradox

@article{Modak2015BlackHE, title={Black hole evaporation: information loss but no paradox}, author={Sujoy Kumar Modak and Leonardo Ort{\'i}z and Igor Pe{\~n}a and Daniel Sudarsky}, journal={General Relativity and Gravitation}, year={2015}, volume={47}, pages={1-55} }

The process of black hole evaporation resulting from the Hawking effect has generated an intense controversy regarding its potential conflict with quantum mechanics’ unitary evolution. A recent set of works by a collaboration involving one of us, have revised the controversy with the aims of, on one hand, clarifying some conceptual issues surrounding it, and, at the same time, arguing that collapse theories have the potential to offer a satisfactory resolution of the so-called paradox. Here we…

Panpsychism is the view that consciousness is a fundamental feature of reality. Panpsychism addresses the fact that no physical theories can ever be able to explain conscious experience in terms of…

Probing the Unruh effect with an accelerated extended system

- PhysicsNature Communications

It is shown how a uniformly accelerated extended system of two coupled spins will evolve to a Gibbs thermal state at the Unruh temperature, which proves that the vacuum state does induce thermalization of an accelerated extension system—which is all one can expect of a legitimate thermal reservoir.

Collapse of the wavefunction, the information paradox and backreaction

We consider the black hole information problem within the context of collapse theories in a scheme that allows the incorporation of the backreaction to the Hawking radiation. We explore the issue in…

It is argued that to leading order in perturbation theory the effect of the back reaction is to modify the Bogoliubov transformation, but not in a way that restores information lost to the black hole.

Information loss, made worse by quantum gravity?

A renormalizable theory of quantum gravity coupled to a dilaton and conformal matter in two spacetime dimensions is analyzed and suggests that the collapsing matter radiates away all of its energy before an event horizon has a chance to form, and black holes disappear from the quantum-mechanical spectrum.
