چکیده
We examine the status of Chern-Simons (or Kodama) state from point view a formulation gravity that uses only real connection and metric variables action. may package into complex self-dual Ashtekar (and will do so to make contact with previous work), but operation is essentially cosmetic can be undone at any step or even bypassed altogether. The action remain (real) Einstein-Cartan action, forgoing addition usual Holst Nieh-Yan) term an imaginary coefficient. It then found constraints are solved by modification which pure phase (in Lorentzian theory, we stress), containing fully gauge-invariant part functional. Thus, for ``real theory'' nonpathological regards most egregious criticisms facing its ``nonreal'' cousin, solving theory. A straightforward also solution in quasitopological theories based on Euler invariant, cosmological constant, $\mathrm{\ensuremath{\Lambda}}$, dynamical. In case it enough shift factor $\mathrm{\ensuremath{\Lambda}}$ wave function inside spatial integral. trick works quasi-Euler theory critical coupling previously identified literature. does not apply quasi-Pontryagin

Noncommutative Chern-simons Soliton
We have studied the noncommutative extension of the relativistic Chern-Simons-Higgs model, in the first non-trivial order in θ, with only spatial noncommutativity. Both Lagrangian and Hamiltonian formulations of the problem have been discussed, with the focus being on the canonical and symmetric forms of the energy-momentum tensor. In the Hamiltonian scheme, constraint analysis and the induced ...
متن کاملChern–Simons Perturbation Theory
We study the perturbation theory for three dimensional Chern–Simons quantum field theory on a general compact three manifold without boundary. We show that after a simple change of variables, the action obtained by BRS gauge fixing in the Lorentz gauge has a superspace formulation. The basic properties of the propagator and the Feynman rules are written in a precise manner in the language of di...

متن کاملReal-time Chern-Simons term for hypermagnetic fields
If non-vanishing chemical potentials are assigned to chiral fermions, then a Chern-Simons term is induced for the corresponding gauge fields. In thermal equilibrium anomalous processes adjust the chemical potentials such that the coefficient of the Chern-Simons term vanishes, but it has been argued that there are non-equilibrium epochs in cosmology where this is not the case and that, consequen...
متن کاملGravitating Chern-Simons vortices.
The construction of self-dual vortex solutions to the Chern-SimonsHiggs model (with a suitable eighth-order potential) coupled to Einstein gravity in (2 + 1) dimensions is reconsidered. We show that the self-duality condition may be derived from the sole assumption g00 = 1. Next, we derive a family of exact, doubly self-dual vortex solutions, which interpolate between the symmetrical and asymme...
