Abstract
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 black hole evaporation effect, and to particle creation processes in the early universe. The last decade has witnessed a phenomenal growth in this subject. This is the first attempt to collect and unify the vast literature that has contributed to this development. All the major technical results are presented, and the theory is developed carefully from first principles. Here is everything that students or researchers will need to embark upon calculations involving quantum effects of gravity at the so-called one-loop approximation level.

Weyl-Gauge Symmetry of Graphene

TL;DR: In this paper, the conformal invariance of the low energy limit theory governing the electronic properties of graphene is explored, and it is noted that the massless Dirac theory in point enjoys local Weyl symmetry, a very large symmetry.

One-loop modified gravity in a de Sitter universe, quantum-corrected inflation, and its confrontation with the Planck result

TL;DR: In this article, a generalized modified gravity model is investigated, where the model Lagrangian is described by a smooth function $f(R, K, \phi)$ of the Ricci scalar $R$, the kinetic term $K$ of a scalar field $\phi$, and the one-loop effective action in the de Sitter background is examined on-shell and off-shell in the Landau gauge.

Renormalized Unruh-DeWitt particle detector models for boson and fermion fields

TL;DR: In this paper, the authors investigated UDW detector models that probe fermionic as well as bosonic fields through both linear and quadratic couplings, and showed how perturbative calculations with UDW detectors can be streamlined through the use of extended Feynman rules that include localized detector-field interactions.

Acoustic white holes in flowing atomic Bose–Einstein condensates

TL;DR: In this article, the authors study acoustic white holes in a steadily flowing atomic Bose-Einstein condensate and obtain a white hole configuration when the flow velocity goes from a super-sonic value in the upstream region to a sub-sonic one in the downstream region, and the correlation pattern of density fluctuations is numerically studied by means of the truncated-Wigner method, which includes quantum fluctuations.

Preferred instantaneous vacuum for linear scalar fields in cosmological space-times

TL;DR: In this article, the problem of defining a preferred vacuum state at a given time for a quantized scalar field in Friedmann, Lemaitre, Robertson Walker (FLRW) space-time is discussed.

Particle Creation by Black Holes

TL;DR: In this article, it is shown that quantum mechanical effects cause black holes to create and emit particles as if they were hot bodies with temperature, which leads to a slow decrease in the mass of the black hole and to its eventual disappearance.

Foundations of the Theory of Dynamical Systems of Infinitely Many Degrees of Freedom, II

TL;DR: The notion of quantum field remains at this time still rather elusive from a rigorous standpoint as mentioned in this paper, and it was recognized very early by Bohr and Rosenfeld that even in the case of a free field, no physical meaning could be attached to the values of the field at a particular point, only the suitably smoothed averages over finite space-time regions had such a meaning.

Evidence for the existence of gravitational radiation from measurements of the binary pulsar psr 1913+16

TL;DR: The results of four years of timing observations of PSR 1913+16 made with the 305m telescope at the Arecibo Observatory at frequencies near 430 and 1410 MHz are summarized in this paper.
