This book presents a comprehensive review of the subject of gravitational effects in quantum
field theory. Although the treatment is general, special emphasis is given to the Hawking …

There is strong evidence that the area of any surface limits the information content of
adjacent spacetime regions, at 1.4× 10 69 bits per square meter. This article reviews the …

The fact that one can associate thermodynamic properties with horizons brings together
principles of quantum theory, gravitation and thermodynamics and possibly offers a window …

Primordial black holes are under intense scrutiny since the detection of gravitational waves
from mergers of Solar-mass black holes in 2015. More recently, the development of …

This paper investigates the thermodynamic behaviors and optical properties of regular black
holes within pure gravity theories, notable for their absence of singularities. Using both …

Thermodynamics is a science concerning the state of a system, whether it is stable,
metastable, or unstable, when interacting with its surroundings. The combined law of …

In the present work we study the geodesic motion and accretion process of a test particle
near an Anti-de Sitter (ADS) BH surrounded by a dark fluid with a Chaplygin-like equation …

Traversable wormholes necessarily require violations of the averaged null energy condition,
this being the definition of “exotic matter.” However, the theorems which guarantee the …
