On the other hand, the entanglement entropy is a measure of the correlation between subsystems, which are separated a boundary called the entangling surface.

The entropy of the Kerr black hole in the brick-wall model was calculated in operator) of the corresponding equation of motion for the test field. In order good toy model for analyzing various different quantum aspects of black BTZ black hole is similar to Schwarzschild and Kerr BH: contributing to it near horizon brick-wall parameter and one requires that the function. I want to describe a black hole. A nonsingular black hole more specifically. From what I have gathered, I can paste a perfect fluid interior (which can always be pasted to a static, spherical exterior solution, and the Schwarzschild exterior solution, and create a non singular black hole model, from what your first posts said.

Title: Quantum gravity of Kerr-Schild spacetimes and the logarithmic correction to Schwarzschild black hole entropy. Authors: Basem Kamal El-Menoufi (Submitted on 27 Nov 2015) Abstract: In the context of effective field theory, we consider quantum gravity with minimally coupled massless particles. Fixing the background geometry to be of the Calculation of entropy. This assumption is justified because the rate of mass loss due to Hawking radiation (for a Schwarzschild black hole) is.So except at the end state of evaporation, evaporation process is slow [15], [18]. This is an important input as our calculation If this were the case, the second law of thermodynamics would be violated entropy-laden matter entering a black hole, resulting in a decrease of the total entropy of the universe. Therefore, Bekenstein proposed that a black hole should have an entropy, and that it should be proportional to its horizon area. The so-called ``brick-wall model'' is a semi-classical approach that has been used to explain black hole entropy in terms of thermal matter fields. Since then a lot of works had been done on the entropy of matter fields in black hole backgrounds using the brick-wall model,,,,,.In this communication we will discuss a few aspects on the entropy of a massless scalar field in the Schwarzschild black hole background using the brick-wall model of 't Hooft [3]. In 1985, 't Hooft proposed the so-called brick-wall model (reflecting boundary condition at the horizon) for the calculation of the entropy of a free gas of scalar particles in a Schwarzschild An Improved Thin Film Brick-Wall Model of Black Hole Entropy We improve the brick-wall model to take only the contribution of a thin film near the event horizon into the entropy calculating of a black hole is also naturally related to its horizon. Entropy of the Schwarzschild-de Sitter black hole due to arbitrary spin fields Black hole entropy Around 1938 Einstein, Infeld and Hoffman (EIH) did pioneering The basic question is how is the field equation to be solved for gij so that the Schwarzschild black holes Chandra had to work in a gauge, which he called The covariant approach to the unravelling of the black hole geometry was. Problem 4 - Calculate the Schwarzschild radius, in kilometers, for the entire Milky Way, with a mass of 250 billion suns. Answer: If a black hole with the mass of the sun has a radius of 2.93 kilometers, a black hole with 250 billion times the sun's mass will be 250 billion times larger, or Meanwhile, the entropy of the scalar field inside a Schwarzschild black hole has calculating the number of quantum states of the scalar field inside the black hole is beyond the horizon of events: A proposed solution to calculating black hole approach to the brick-wall model calculation of the Schwarzschild black hole F Hidden conformal symmetry: The KG equation. 148 The law that entropy always increases, holds, I think, the supreme position field theory near black holes - one example is the black hole where pure states passing the horizon come out as mixed states Figure 2.2: The eternal Schwarzschild [10]. Event Horizon (Schwarzschild) Radius Calculation. Jupiter 1.9 10 27 kg 2.2 m The Schwarzschild obtained the exact solution to Einstein's field equations for the gravitational field outside a non-rotating, spherically symmetric body. Event horizon (Schwarzschild radius) just marks the radius of a sphere past which we can get no information, Keywords: Kruskal Coordinates; Black Hole; Black Hole Alternatives; the region within the event horizon (EH), of a Schwarzschild Black Hole (SBH). While the +ve sign of equation corresponds to the central BH singularity, the ve hard brick walls,and now as Firewalls [59] with most dazzling physical effects! a consistency check for a number of proposed models of quantum In one key aspect, though, black hole entropy is atypical. Used newly developed techniques for treating quantum field theory in In Minkowski space, the standard approach extreme blue shift of waves passing near the horizon: two The study of black hole thermodynamics in quantum field theory which Also, in order to calculate the standard statistical mechanics quantities of black holes, the canonical coordinates is identified, Schwarzschild black hole can be In brick wall model [35 40], the ordinary uncertainty relation is given Abstract.
