Holographic Paradigm and Black Hole Thermodynamics

The holography principle says that the quantum field theories in the d-dimensional spacetime can equivalently be described by the one-dimension higher d+1 dimension classical gravity system with the negative cosmological space-time (so-called anti-de Sitter (AdS) space). For example, the coupling constant in the quantum field theory is related to the “size” of the AdS space. This provides a new paradigm to describe the strongly interacting quantum system, such as nuclear interaction or strongly correlated system, in terms of a corresponding classical gravity system. The black hole, a long-time studied object, is known to have thermal properties with the so-called Hawking temperature. Hence, the finite temperature quantum system will be related to the gravity theory with the black hole. The crucial step in relying on this new paradigm is finding the right gravity system. In this presentation, we will explain the underlying key ideas and concepts of the holographic principle and the black hole thermodynamics with some examples.
