Thesis Title | Hawking radiation in present and early universe |

Thesis Abstract | The project will analyse Hawking's prediction of black hole radiation and related thermal effects in curved spacetime quantum field theory in situations where the system is far from equilibrium and time-dependence has a strong role. Specific examples include the onset of Hawking radiation when a star collapses to form a black hole, the time evolution of Hawking radiation during black hole evaporation, and the decay of thermality due to expansion in the early universe. On the technical side, the project will to clarify the correspondence between phenomena seen by model particle detectors and phenomena seen by the technically complementary but physically less transparent Bogoliubov transformation formalism, pioneered in the gravitational context in Hawking's original derivation of black hole radiation. On the conceptual side, the project will provide insight into the microphysical origin black hole entropy and other thermodynamical properties associated with black holes, in a non-equilibrium setting. These insights will guide the search for a fundamental, quantum mechanical theory of gravity, from which Hawking radiation should eventually be derivable as an effective semiclassical, low-energy effect. |
