Abstract
Near the event horizon of a black hole, the effective theory is two dimensional conformal theory. Here we show that the holographic modes characterising this underlying conformal symmetry and the basic definition of entropy in statistical mechanics lead the equipartition law of energy. We also show that is proportional to the gravity action which suggests the emergent nature of gravity. This is further bolstered by expressing the generalised Smarr formula as a thermodynamic relation, , where is the Hawking temperature and is shown to be the Komar energy.
