Black Hole Entropy from Non-dirichlet Sectors, and a Bounce Solution

Abstract: In a series of recent works the relevance of gravitational boundary degrees of freedom and their dynamics in gravity quantization and black hole information has been explored. In this work we further the progress by keenly focusing on the boundary degrees of freedom as the origin of black hole entropy. Wald's entropy formula is scrutinized, and the reason that the Wald's formula correctly captures the entropy of a black hole is examined. Afterwards, limitations of the Wald's method are discussed; a coherent vi… Show more

“…The UCA charges have support on a boundary located at a finite distance, as is the case for the quantum Hall effect discussed above. They are believed to play an important role in gauge theories, holography, black hole physics, quantum gravity and much more [85][86][87][88][89][90][91][92][93][94][95][96][97][98][99][100][101][102][103][104]. One of the most intriguing areas in which they are believed to play a role is entanglement entropy.…”
