Regular Frames for Spherically Symmetric Black Holes Revisited

Alexey V. Toporensky et al.

Summary: This study considers the spacetime of a spherically symmetric black hole with a simple horizon. Due to the failure of a standard coordinate frame near the horizon, continuation and construction of regular frames are required. It is shown that Kruskal-Szekeres and Lemaitre frames stem from the same root, providing a more general scheme.

Quantum evolution of the Hawking state for black holes

Steven B. Giddings et al.

Summary: In this article, a general description of the evolving quantum state of a Schwarzschild black hole is given using the quantum field theory approximation. The description depends on the choice of time slices, coordinates on the slices and mode bases. The evolving state can simplify the analysis and has connections to information-theoretic investigation of black hole evolution.

Maximal extension of the Schwarzschild metric: From Painleve-Gullstrand to Kruskal-Szekeres

Jose P. S. Lemos et al.

Summary: This study demonstrates the continuous linkage between the Painleve-Gullstrand partial extension and the Kruskal-Szekeres maximal analytical extension, providing a unified picture of the maximal extension of the Schwarzschild metric. By utilizing a coordinate system with two time coordinates parametrized by the same energy per unit mass E, this integrated description reveals the relationship between different families of extensions based on the energy E of timelike geodesics. The Novikov-Lemaitre family and the E family of extensions exhibit distinct characteristics and behaviors, with implications for the spacetime structures they lead to.

Schrodinger evolution of two-dimensional black holes

Steven B. Giddings

Summary: This paper systematically examines the evolving quantum state of two-dimensional black holes, focusing on the CGHS model and generalizing to higher dimensions. By studying the state's dynamic evolution at intermediate times in the Schrodinger picture, the paper offers insights into gravitational dynamics and the evolution of quantum matter on background geometry. The explicit description of the evolving state provides connections to information theory and potential corrections to unitarize evolution in the presence of new quantum gravity effects.

Flow and Peculiar Velocities for Generic Motion in Spherically Symmetric Black Holes

A. V. Toporensky et al.

Summary: This methodological paper extends previous results obtained for pure radial motion to consider the geodesic motion of particles in spherically symmetric black hole space-times, including nonradial motion and the possibility of an observer having nonzero angular momentum. The approach provides a simple physical interpretation of redshifts (blueshifts) inside the horizon, including the region near the singularity, and is consistent with recent results obtained by direct calculations.
