Geometric Structures and Loop Variables in (2+1)-Dimensional Gravity
S. Carlip
This paper is a review of the relationship between the metric formulation of (2+1)-dimensional gravity and the loop observables of Rovelli and Smolin. I emphasize the possibility o…
Notes on the (2+1)-Dimensional Wheeler-DeWitt Equation
Steven Carlip
In contrast to other approaches to (2+1)-dimensional quantum gravity, the Wheeler-DeWitt equation appears to be too complicated to solve explicitly, even for simple spacetime topol…
Six ways to quantize (2+1)-dimensional gravity
S. Carlip
We do not yet know how to quantize gravity in 3+1 dimensions, but in lower dimensions we face the opposite problem: many of the approaches originally developed for (3+1)-dimensiona…
Chern-Simons States in Topologically Massive Gauge Theories
S. Carlip
The set of degenerate ground states of an arbitrary nonabelian topologically massive gauge theory is shown to be in one-to-one correspondence with the Hilbert space of the associat…
Chern-Simons States and Topologically Massive Gauge Theories
M. Asorey, S. Carlip, F. Falceto
In an abelian topologically massive gauge theory, any eigenstate of the Hamiltonian can be decomposed into a factor describing massive propagating gauge bosons and a Chern-Simons w…
Real Tunneling Solutions and the Hartle-Hawking Wave Function
S. Carlip
A real tunneling solution is an instanton for the Hartle-Hawking path integral with vanishing extrinsic curvature (vanishing ``momentum'') at the boundary. Since the final momentum…
