There are numerous derivations of the Hawking effect available in the literature. They emphasise different features of the process, and sometimes make markedly different physical assumptions. This article presents a "minimalist" argument, and strips the derivation of as much excess baggage as possible. All that is really necessary is quantum physics plus a slowly evolving future apparent horizon (not an event horizon). In particular, neither the Einstein equations nor Bekenstein entropy are… 

Noncommutative FRW Apparent Horizon and Hawking Radiation

In the context of noncommutative (NCG) gauge gravity, and using a cosmic time power law formula for the scale factor, a Friedman-Robertson-Walker (FRW) like metric is obtained. Within the fermions

Hawking Radiation -- Revisited

In this paper we revisited Hawking radiation in the light of the original calculations of Hawking and Wald and found that some additional insights can be gained. We review a "derivation" of the field

Hawking temperature for a large class of black holes (Schwarzschild, Reissner–Nordström, (Anti) de Sitter, with spherical, toroidal and hyperboloidal topologies) is computed using only laws of

Entropy/Information flux in Hawking radiation

TLDR
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.

Quantum effects across dynamical horizons

We present a generalization of the Hawking effect for dynamical trapping horizons by calculating the tunneling rate in the Hamilton–Jacobi formalism. It turns out that all horizons classified by

Sensitivity of Hawking radiation to superluminal dispersion relations

We analyze the Hawking radiation process due to collapsing configurations in the presence of superluminal modifications of the dispersion relation. With such superluminal dispersion relations, the

Local approach to Hawking radiation

We consider an approach to the Hawking effect which is free of the asymptotic behavior of the metric or matter fields, and which is not confined to one specific metric configuration. As a result, we

Thermodynamics of spacetime from minimal area

Motivated by exploring the interface between thermodynamics of spacetime and quantum gravity effects, we develop a heuristic derivation of Hawking temperature and Bekenstein entropy from the

On the paradox of Hawking radiation in a maximally extended Schwarzschild solution

This paper considers the effect of Hawking radiation on an eternal black hole - that is. a maximally extended Schwarzschild solution. Symmetry considerations that hold independent of the details of

On the Hawking effect

In terms of the Painlev´e-Gullstrand-Lemaˆıtre coordinates a rather general scenario for the gravitational collapse of an object and the subsequent formation of a horizon is described by a manifestly

Hawking radiation without trans-Planckian frequencies.

TLDR
The mathematical and physical origin of Unruh's result is revealed, an alternative truncation scheme which may be more appropriate for black hole physics is proposed and analyzed and the thermal Hawking radiation remains unaffected even though trans-Planckian energies no longer appear.

Hawking radiation As tunneling

TLDR
A short and direct derivation of Hawking radiation as a tunneling process, based on particles in a dynamical geometry, respects conservation laws, but the exact spectrum is not precisely thermal.

Hawking Radiation without Black Hole Entropy

Hawking radiation is a purely kinematic effect that is generic to Lorentzian geometries containing event horizons; it is independent of dynamics. On the other hand, the classical laws of black hole

Method of complex paths and general covariance of Hawking radiation

We apply the technique of complex paths to obtain Hawking radiation in different coordinate representations of the Schwarzschild space–time. The coordinate representations we consider do not possess

A generalization of the classical approach of barrier penetration introduced by Klein, Sauter, Heisenberg, and Euler to curved spaces endowed with future horizons is given. This technique allows one

Using tunneling concepts which account for particle production in the cases of an accelerated detector and a static electric Field in Minkowski space, the more elusive case of black hole evaporation

Hawking-Unruh Thermal Radiance as Relativistic Exponential Scaling of Quantum Noise ∗

The Hawking-Unruh effect of thermal radiance from a black hole or observed by an accelerated detector is usually viewed as a geometric effect related to the existence of an event horizon. Here we

This paper examines various aspects of black-hole evaporation. A two-dimensional model is investigated where it is shown that using fermion-boson cancellation on the stress-energy tensor reduces the
