Investigation of the entropy of a black hole as a Noether charge of diffeomorphism symmetry Banafsheh Salehi banafsheh salehi@ph iut ac ir May 8 2018 Department of Physics Isfahan University of Technology Isfahan 84156 83111 Iran University Code IUT 77142 Degree M S c Language Farsi supervisor Dr A Shirzad Shirzad@cc iut ac ir Abstract Black hole thermodynamics is one of the most important topics of theoritical physics in resent decades Theoretically black hole thermodynamics provides a background for studying gravitational theory and quantum gravity Hawking showed that the black holes obey a set of four thermodynamical laws similar to ordinary thermodynamics In this thesis reviewing the basics of general relativity we try to get a better understanding of the meaning of the first law of black hole thermodynamics For this reason we use the Wald approach implying the black hole entropy as a Noether charge due to diffeomorphism symmetry In this approach considering the isometries and symmetries of the system in the framework of covariant phase space we ascribe a Noether current and a Noether charge to lacal symmetry of diffeomorphism associated to a definit killing vector Then considering a timelike killing vector we show that the Noether charge due to the corresponding diffeomorphism can be interpreted as the entropy of the black hole We can see that this quantity is the same as Bekenstain Hawking formula for the Hilbert Einstein theory This result is achieved by considering asymptotic flat metric boundary conditions as well as a stationary black hole with a bifurcation killing horizon We also prac ticed this method for dilaton gravity to find the corresponding black hole entropy Keywords Black hole entropy diffeomorphism symmetry Noether current Noether charge surfacegravity bifurcation killing horizon
