Loop Quantum Gravity An Introduction We compute this number explicitly from first principles, for a schwarzschild black hole, using nonperturbative quantum gravity in the loop representation. we obtain a black hole entropy proportional to the area, as in the bekenstein hawking formula. Some applications and results of loop quantum gravity are presented: loop quantum cosmology and the removal of singularities, black hole entropy, and the modern spin foam formalism. the current status of loop quantum gravity research is discussed.
Loop Quantum Gravity And Entropy In this paper, we introduced a class of states in loop quantum gravity whose entanglement entropy for a bounded region scales as the area of the boundary (number of degrees of freedom) and whose correlation functions between distant spins are non trivial. Defining entanglement entropy in loop quantum gravity entanglement entropy sr (| i) = tr(⇢ log ⇢) characterizes the statistical fluctuations in a sub algebra of observables. To understand the deep structure of loop quantum gravity (lqg) [1], in particular the holographic principle and quantum black holes, it is necessary to analyze in detail the entropy counting. We give an account of the state of the art about black hole entropy in loop quantum gravity. this chapter contains a historical summary and explains how black hole entropy is described by relying on the concept of isolated horizon, with an emphasis on different.

We give an account of the state of the art about black hole entropy in loop quantum gravity. this chapter contains a historical summary and explains how black hole entropy is described by relying on the concept of isolated horizon, with an emphasis on different. I will argue in this contribution that the existing model in loop quantum gravity (lqg) not only gives a plausible explanation for the behaviour of black hole entropy as a function of the area but also makes some intriguing predictions. A problem that has been repeatedly tied to quantum gravity, and which loop quantum gravity is able to address, is the problem of the ultraviolet infinities in quantum field theory. This chapter is devoted to the application of the loop quantum gravity (lqg) formalism to a statistical mechanical treatment of bh microscopic degrees of freedom (dof) in order to derive their semi classical and continuum properties within a quantum gravity approach. The last few years have seen the techniques of loop quantum gravity applied to a growing number of problems. they have been used to compute the entropy of various sorts of black holes, including those with non minimally coupled matter, for which the entropy is not proportional to the area.
