N-body Gravity and the Schroedinger Equation
P. S. Farrugia, R. B. Mann, T. C. Scott
We consider the problem of the motion of bodies in a self-gravitating system in two spacetime dimensions. We point out that this system can be mapped onto the quantum-mechanica…
Perturbative Quantum Gravity Coupled to Particles in (1+1)-Dimensions
R. B. Mann, M. B. Young
We consider the problem of (1+1)-dimensional quantum gravity coupled to particles. Working with the canonically reduced Hamiltonian, we obtain its post-Newtonian expansion for two…
On the Standard Approach to Renormalization Group Improvement
F. A. Chishtie, V. Elias, R. B. Mann +2
Two approaches to renormalization-group improvement are examined: the substitution of the solutions of running couplings, masses and fields into perturbatively computed quantities…
Accelerating Taub-NUT and Eguchi-Hanson solitons in four dimensions
Brenda Chng, Robert Mann, Cristian Stelea
We construct new solutions of the vacuum Einstein field equations in four dimensions via a solution generating method utilizing the SL(2,R) symmetry of the reduced Lagrangian. We a…
Note on counterterms in asymptotically flat spacetimes
Dumitru Astefanesei, Robert B. Mann, Cristian Stelea
We consider in more detail the covariant counterterm proposed by Mann and Marolf in asymptotically flat spacetimes. With an eye to specific practical computations using this counte…
Higher Gauge Theory and Gravity in (2+1) Dimensions
R. B. Mann, Eugeniu M. Popescu
Non-abelian higher gauge theory has recently emerged as a generalization of standard gauge theory to higher dimensional (2-dimensional in the present context) connection forms, and…
