The horizon of the McVittie black hole: on the role of the cosmic fluid modeling
European Physical Journal C: Particles and Fields, 2020 In this paper, we investigate the existence and time evolution of the cosmological and event horizons in a McVittie universe whose expansion is driven by the Redlich–Kwong, (Modified) Berthelot, Dieterici, and Peng–Robinson fluids, respectively.

Quasinormal modes in two-photon autocorrelation and the geometric-optics approximation
European Physical Journal C: Particles and Fields, 2022 In this work, we study the black hole light echoes in terms of the two-photon autocorrelation and explore their connection with the quasinormal modes. It is shown that the above time-domain phenomenon can be analyzed by utilizing the well-known frequency-

Horizon curvature and spacetime structure influences on black hole scalarization
European Physical Journal C: Particles and Fields, 2021 Black hole spontaneous scalarization has been attracting more and more attention as it circumvents the well-known no-hair theorems. In this work, we study the scalarization in Einstein–scalar-Gauss–Bonnet theory with a probe scalar field in a black hole ...

Curvature invariants and lower dimensional black hole horizons
European Physical Journal C: Particles and Fields, 2019 It is known that the event horizon of a black hole can often be identified from the zeroes of some curvature invariants. The situation in lower dimensions has not been thoroughly clarified.

Diagnosing quantum phase transitions via holographic entanglement entropy at finite temperature
European Physical Journal C: Particles and Fields, 2023 We investigate the behavior of the holographic entanglement entropy (HEE) in proximity to the quantum critical points (QCPs) of the metal-insulator transition (MIT) in the Einstein–Maxwell-dilaton-axions (EMDA) model.

THE OMEGA POINT AS ESCHATON: ANSWERS TO PANNENBERG'S QUESTIONS FOR SCIENTISTS
Zygon, 1989 . I present an outline of the Omega Point theory, which is a model for an omnipresent, omniscient, omnipotent, evolving, personal God who is both transcendent to spacetime and immanent in it, and who exists necessarily.

A complementary third law for black hole thermodynamics
European Physical Journal C: Particles and Fields, 2019 There are some examples in the literature, in which despite the fact that the underlying theory or model does not impose a lower bound on the size of black holes, the final temperature under Hawking evaporation is nevertheless finite and nonzero. We show

Tree and 1-loop fundamental BCJ relations from soft theorems
European Physical Journal C: Particles and Fields, 2023 We provide a new derivation of the fundamental BCJ relation among double-color-ordered tree amplitudes of bi-adjoint scalar theory, based on the leading soft theorem for external scalars. Then, we generalize the fundamental BCJ relation to 1-loop Feynman

Note on scalar–graviton and scalar–photon–graviton amplitudes
European Physical Journal C: Particles and Fields, 2020 In this short note, we propose an algorithm based on the expansions of amplitudes, the dimensional reduction technique and the approach by differential operators, to calculate the tree level scalar–graviton amplitudes with two massive scalars and the ...

Joule-Thomson expansion for hairy black holes
Physics Letters B, 2021 We study the Joule-Thomson (JT) expansion of hairy black hole in AdS5 spacetime. We first investigate the inversion temperature and isenthalpic curve in the P−T plane of the system. The isenthalpic curves are divided into two parts by the inversion curve,
