String Theory: Defining A Black Hole

Di: Amelia

We define a notion of `quantum entanglement index‘ with the aim to compute it for black hole horizons in string theory at one-loop order using the stringy replica method. The study of black holes in string theory has led to the discovery of deep and surprising connec-tions between black holes and modular forms—which are two classical, a priori unrelated, Black hole, cosmic body of extremely intense gravity from which nothing, not even light, can escape. It can be formed by the death of a massive star wherein its core

How Black Holes Work: The Physics Behind Nature’s Monsters

The Bekenstein-Hawking entropy or black hole entropy is the amount of entropy that must be assigned to a black hole in order for it to comply with the laws of thermodynamics Leonard Susskind is Felix Block Professor of Physics at Stanford University. Along with other accomplishments, he is among the fathers of such revolutionary concepts in physics

String theory was first studied in the late 1960s as a theory of the strong nuclear force, before being abandoned in favor of quantum chromodynamics. Subsequently, it was realized that the Black hole thermodynamics is the study of the properties and behavior of black holes in relation to temperature, entropy, and energy, within the framework of string theory. It involves the analysis
