碩士 === 國立中央大學 === 物理學系 === 103 === In this thesis we mainly study the production of pair particles carrying energy, electricity and angular momentum of the background, which is a Kerr-Newman (KN) black hole. Firstly we review the quantum field theory in curved spacetime to discuss the vacuum particle production by connecting quantum field at two different points in spacetime via the Bogoliubov relation. More precisely, the non-vanishing $B$ coefficients indicates the appearance of the particle production. We then analysis the charged scalar production appearing at the near-horizon region of near-extremal KN black hole via the ratios of the fluxes of in- and out-going propagating modes at two boundaries. From the conservation of flux one can obtain a expressions analogy to the Bogoliubov relation. Thus the Bogoliubov coefficients, consequently the essential physical quantities, such as vacuum persistence, mean number of production and absorption cross section, can be obtained.
