The 2+1 Kepler Problem and Its Quantization
Jorma Louko, Hans-Juergen Matschull
We study a system of two pointlike particles coupled to three dimensional Einstein gravity. The reduced phase space can be considered as a deformed version of the phase space of tw…
The Phase Space Structure of Multi Particle Models in 2+1 Gravity
Hans-Juergen Matschull
What can we learn about quantum gravity from a simple toy model, without actually quantizing it? The toy model consists of a finite number of point particles, coupled to three dime…
(2+1)-dimensional Einstein-Kepler problem in the centre-of-mass frame
Jorma Louko, Hans-Juergen Matschull
We formulate and analyze the Hamiltonian dynamics of a pair of massive spinless point particles in (2+1)-dimensional Einstein gravity by anchoring the system to a conical infinity,…
The Anti-de Sitter Gott Universe: A Rotating BTZ Wormhole
S. Holst, H. -J. Matschull
Recently it has been shown that a 2+1 dimensional black hole can be created by a collapse of two colliding massless particles in otherwise empty anti-de Sitter space. Here we gener…
On the relation between 2+1 Einstein gravity and Chern Simons theory
Hans-Juergen Matschull
A simple example is given to show that the gauge equivalence classes of physical states in Chern Simons theory are not in one-to-one correspondence with those of Einstein gravity i…
Black Hole Creation in 2+1 Dimensions
Hans-Juergen Matschull
When two point particles, coupled to three dimensional gravity with a negative cosmological constant, approach each other with a sufficiently large center of mass energy, then a BT…
