Thermalization of Poincar\'e Vacuum State and Fermion Emission from AdS3 Black Holes in Bulk-Boundary Correspondence
Abstract
The greybody factors for spin 1/2 particles in the BTZ black holes are discussed from 2D CFT in bulk-boundary correspondence. It is found that the initial state of spin 1/2 particle in the BTZ black holes can be described by the Poincar\'e vacuum state in boundary 2D CFT, and the nonlinear coordinate transformation causes the thermalization of the Poincar\'e vacuum state. For special case, our results for the greybody factors agree with the semiclassical calculation.
