About 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.
• 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.
• 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.

Classical and Quantum Gravity Exact Solutions Policy:

In the field of classical relativity, the discovery of a new exact solution does not justify publication simply for its own sake. Justification for publishing a new solution would be provided by showing for example that it has an interesting physical application or unusual geometrical properties, or that it illustrates an important mathematical point. The onus is on the author to provide convincing evidence that the solution is in fact new.

The development of a new technique or formalism for finding solutions of the field equations does not represent a sufficient advance to justify publication, unless the method is applied successfully.

Classical and Quantum Gravity welcomes submissions of the following article types:

• Research Papers: reports of high-quality original research with conclusions representing a significant advance in the field.
• Letters: brief articles describing a substantial advance in the field. All letters must meet one of the following publication criteria: report significant new results or an important new discovery; make important advances on or provide a solution to a critical issue; report findings of major interest to a specific community or demonstrate a new idea, experimental technique, theory or model which will have a potentially significant impact.
• Focus issue articles: articles which will form a special collection of papers on a specific theme, often invited by the issue’s Guest Editor(s).
• Topical reviews: comprehensive review articles normally commissioned by the Editorial Board.
• Brief reviews: short review articles reviewing rapid, recent progress normally commissioned by the Editorial Board.
• Comments: brief articles that comment on a previously published Classical and Quantum Gravity article. The authors of the criticised paper may be invited to submit a Reply in response.
• Notes: brief articles that make a short, interesting point, which would not normally merit publication as a full Paper but still make a useful and novel addition to the literature. They may highlight an interesting point, clarify a common misunderstanding or confusion, or present a short new result. Unlike Comments, they do not relate to a specific published article.

This journal publishes Focus Issues, special collections of articles on a specific theme, often invited by the issue’s Guest Editor(s).
