Abstract:
We consider a nonstandard D=2+1D=2+1 gravity described by a translational Chern--Simons action, and couple it to the nonrelativistic point particles. We fix the asymptotic coordinate transformations in such a way that the space part of the metric becomes asymptotically Euclidean. The residual symmetries are (local in time) translations and rigid rotations. The phase space Hamiltonian HH describing two-body interactions satisfies a nonlinear equation H=H(x,p;H)H={\cal H}(\vec{x},\vec{p};H) what implies, after quantization, a nonstandard form of the Schr\"{o}dinger equation with energy-dependent fractional angular momentum eigenvalues. Quantum solutions of the two-body problem are discussed. The bound states with discrete energy levels correspond to a confined classical motion (for the planar distance between two particles rr0r\leq r_0) and the scattering states with continuous energy correspond to classical motion for r>r0r>r_0.
