CLASSICAL AND QUANTUM GRAVITY

Classical and Quantum Gravity ，welcomes original research articles on all branches of gravitational physics and the theory of spacetime. The readership of the journal is broad, comprising gravitational theorists and experimentalists in physics, mathematics and cosmology. All articles should be of interest to this broad readership and should contain a summary that places the findings in the wider context of gravitational physics. The detailed coverage of the journal includes, but is not limited to: Classical general relativity: all aspects including initial-value problems, techniques and applications of numerical relativity, exact solutions, topology and causal structure, singularities, canonical and other formalisms, Regge calculus, twistors, dynamical triangulation and other simulation methods. Exact Solutions policy. Applications of relativity: including relativistic astrophysics, gravitational radiation, gravitational lenses, black holes and collapsed objects, and physical processes in their vicinity. Experimental gravitation: including gravitational wave detection, tests of gravitational theories, and articles on data analysis and instrumentation with a clear relevance to gravitation. Further details. Cosmology and the early universe: including particle physics, grand unified theories and phase transitions, inflationary cosmology, theories of galaxy formation and large-scale structure, cosmic microwave background radiation, cosmic strings and topological defects, and cosmic topology. Quantum gravity: all aspects including canonical and covariant quantization, quantum field theory in curved spacetime, semiclassical quantization, topological effects, gauge and gravitational anomalies, quantum cosmology and the quantum theory of black holes and information loss. Supergravity, superstrings and supersymmetry: including the structure of string theory, M-theory and its ramifications, conformal field theory, worldsheet symmetries, string vacua, compactifications and phenomenological applications, p-brane dynamics, nonperturbative aspects of string theory and M-theory. Mathematical physics: relevant to gravitation, specifically gauge-covariant systems, strings and extended objects, constrained Hamiltonian systems, BRST quantization, geometric quantization, renormalization, path integrals, geometry and topology of field theories, instantons and non-linear sigma models, and differential geometry relevant to gravitation.
