TOPIC | Eastern Hemisphere Colloquium of Geometry and Physics (EHCGP)ㅣSymmetry-Resolved Density of States | ||
소개 및 안내사항Content | It is well-known that the density of states of a unitary quantum field theory has a universal behavior at high energy. In two dimensions, it is known as the Cardy formula. When the theory has a global symmetry, it is interesting to find out how the Hilbert space is decomposed into irreducible representation of the symmetry. In this talk, I will derive universal formulas regarding the decomposition of states at high energy. The formulae are applicable to any unitary quantum field theory in any spacetime dimensions. When the AdS/CFT correspondence applies, our formulae agree with the entropy formula for the Kerr and Reissner-Nordstrom black holes. We also settle some question on the Reissner-Nordstrom black hole. |
