Two Particle Quantummechanics in 2 + 1 Gravity using Non Commuting Coordinates

چکیده

We find that the momentum conjugate to the relative distance between two gravitating particles in their center of mass frame is a hyperbolic angle. This fact strongly suggests that momentum space should be taken to be a hyperboloid. We investigate the effect of quantization on this curved momentum space. The coordinates are represented by non commuting, Hermitian operators on this hyperboloid. We also find that there is a smallest distance between the two particles of one half times the Planck length.

Non-commuting coordinates in vortex dynamics and in the Hall effect related to “exotic” Galilean symmetry

Vortex dynamics in a thin superfluid 4He film as well as in a type II superconductor is described by the classical counterpart of the model advocated by Peierls, and used for deriving the ground states of the Fractional Quantum Hall Effect. The model has non-commuting coordinates, and is obtained by reduction from a particle associated with the “exotic” extension of the planar Galilei group. 1 ...

The dependence of velocity on momentum for the free massive particle obeying the κ-Poincaré Poisson symmetry is calculated in terms of intrinsic non-commuting space-time coordinates and shown to have a monotonic character, with upper limit of velocity equal to

One-particle Hilbertspace of 2+1 dimensional gravity using non-commuting coordinates

In 1963 Staruszkiewicz [1] considered general relativity in 2+1 dimensions for the first time. He solved the gravitational field surrounding a point-particle and found that is represents a conical spacetime. The subject was revived in 1984 by Deser, Jackiw and ’t Hooft [2] where it was shown that multiparticle solutions can be constructed by cutting wedges out of spacetime and identifying the b...

Our previous " exotic " particle, together with the more recent anomalous anyon model (which has arbitrary gyromagnetic factor g) are reviewed. The non-relativistic limit of the anyon generalizes the exotic particle which has g = 0 to any g. When put into planar electric and magnetic fields, the Hall effect becomes mandatory for all g = 2, when the field takes some critical value.

Classical solutions of gravitating Chern - Simons electrodynamics ∗

We discuss the reduction of gravitating Chern-Simons electrodynamics with two commuting Killing vectors to a dynamical problem with four degrees of freedom, and present regular particle-like solutions. In three space-dimensions, the abelian Higgs model coupled to Einstein gravity is known to admit static multi-vortex solutions [1]. Stationary vortex solutions arise [2] when a Chern-Simons term ...
