- Gravitation and particle physics
- Tests of gravitational theory
- Black holes
- Quantum gravity and string theory
Research is presently directed in three areas:
- New tests of the equivalence principle are being designed and investigated. Such tests provide us with important information about the gravitational force, and may give some clues as to the structure of quantum gravity. Specific examples include gravitational redshifts of quantum vacuum energies, non-metric effects on anomalous magnetic moments, gravitational depolarizatinon of polarized light and neutrino flavour mixing due to gravitational effects.
- Physical properties of black holes are being studied as a means of gaining insight into quantum gravity. The formulation of the thermodynamics of gravitating systems of finite size (such as a black hole in a box) is being carried out to this end. Pair production of black holes and quantum corrections to the laws of thermodynamics are being investigated as a means of gaining a fundamental understanding of the origin of black hole entropy.
- Theories of lower dimensional gravity are being investigated. Such theories model many important conceptual elements of classical and quantum gravity in a context that is mathematically simple and elegant. Specific projects include a study of the N-body problem, gravitational collapse, dilatonic black holes, and interior structure of black holes. Lower-dimensional black holes.
