Abstract

Canonical quantization of spherically-symmetric Ashtekar-Wheeler-DeWitt midisuperspace theory is performed. Semiclassical states, with integration constant identified with the mass parameter of black holes, are solved exactly from the Hamilton-Jacobi equation. These states can be matched to Schwarzschild spacetimes in usual standard spherically-symmetric form and also in Painleve-Gullstrand form. The Hamilton function remains well-defined at the classical singularity; and it has an imaginary contribution (independent of the Immirzi parameter in Ashtekar-Barbero theory) which can be interpreted as yielding the correct Bekenstein-Hawking entropy-area relation.
