[HTML][HTML] Kink solutions in generalized 2D dilaton gravity

Y Zhong, H Guo, YX Liu - Physics Letters B, 2024 - Elsevier
We study static kink solutions in a generalized two-dimensional dilaton gravity model, where
the kinetic term of the dilaton is generalized to be an arbitrary function of the canonical one …

Evaporation and information puzzle for 2D nonsingular asymptotically flat black holes

M Cadoni, M Oi, AP Sanna - Journal of High Energy Physics, 2023 - Springer
A bstract We investigate the thermodynamics and the classical and semiclassical dynamics
of two-dimensional (2D), asymptotically flat, nonsingular dilatonic black holes. They are …

Black bounces and remnants in dilaton gravity

M Fitkevich - Physical Review D, 2022 - APS
We propose a family of dilaton gravity models possessing bouncing solutions with interiors
connecting separate asymptotically flat regions. We demonstrate that inner Cauchy horizons …

Geodesically completing regular black holes by the Simpson–Visser method

K Pal, K Pal, T Sarkar - General Relativity and Gravitation, 2023 - Springer
Regular black holes are often geodesically incomplete when their extensions to negative
values of the radial coordinate are considered. Here, we propose to use the Simpson–Visser …

Nonsingular and deformed black holes Fundamental aspects and phenomenology

M Oi - 2024 - iris.unica.it
Einstein's theory of gravity, general relativity, stands as one of the most successful and
enduring pillars of modern physics. Its predictions have consistently aligned with a vast array …

Analysis of the Kerr-Newman Diagram. Unravelling the Interior of a Black Hole

HG Flores, H Jain, P Mahapatra, MIG de Souza - 2024 - preprints.org
Here we will explain the correlation between the Kerr-Newman diagram and the theory: RLC
electrical modelling of a black hole and the early universe. We will develop a black hole …

Introduction to Conformal Geometry and Penrose Diagrams

D Guerrero Domínguez - 2022 - diposit.ub.edu
[en] Conformal geometry is the branch of mathematics that studies the transformations on
manifolds that preserve the angles. It has a myriad of applications, both in mathematics and …
