We investigate an entangled system, which is analogous to a composite system of a black hole and Hawking radiation. If Hawking radiation is well approximated by an outgoing particle generated from pair creation around the black hole, such a pair creation increases the total number of states. There should be a unitary mechanism to reduce the number of states inside the horizon for black hole evaporation. Because the infalling antiparticle has negative energy, as long as the infalling…

It is shown that enough mixing is an essential condition to make the Hayden-Preskill protocol functionally work, and the original conjecture of Hayden and Preskill is explicitly demonstrated.

This paper provides several interpretations of the phenomenon of evaporating black holes and concludes that the statistical entropy is greater than the areal entropy; a monster is formed.

### Causal structures and dynamics of black-hole-like solutions in string theory

• Physics

We investigate spherically symmetric solutions in string theory. Such solutions depend on three parameters, one of which corresponds to the asymptotic mass while the other two are the dilaton and

### Nonextensive black hole entropy and quantum gravity effects at the last stages of evaporation

It is shown that when introducing GUP effects, both R\'enyi entropy and temperature associated with black holes have finite values at the end of the evaporation process.

Accelerating mirrors provide a simple conceptual laboratory for studying particle production and the relation between trajectory and particle, energy, and entropy fluxes. We focus on the relation

A new solution for an analytic spectrum of particle creation by an accelerating mirror (dynamical Casimir effect) is given. It is the first model to simultaneously radiate thermally and emit a fini

### Constructing a counterexample to the black hole complementarity

We propose a regular black hole whose inside generates a de Sitter space and then is finally frustrated into a singularity. It is a modified model which was suggested originally by Frolov, Markov,

In this paper, we discuss the black hole complementarity and the firewall proposal at length. Black hole complementarity is inevitable if we assume the following five things: unitarity, entropy-area

There are a number of similarities between black-hole physics and thermodynamics. Most striking is the similarity in the behaviors of black-hole area and of entropy: Both quantities tend to increase

• Physics

It is argued (via consideration of other, non-Markovian models) that conservation of energy and momentum for all states is not fundamentally incompatible with causality in dynamical models in which pure states evolve to mixed states.

The key technical aspect of the calculation is a variant of the “average subsystem” approach developed by Page, which extends beyond bipartite pure systems, to a tripartite pure system that considers the influence of the environment.
