Generation of a QCD - induced Chern - Simons - like term in QED
نویسنده
چکیده
After briefly reviewing the dynamical generation of a topological Chern-Simons (CS) term in QED 3 the possibility of a Chern-Simons-like term generation in the QED 4 Lagrangian by quark loops interacting with a non-abelian background field of an SU (2) model of QCD is demonstrated.

The structure of radiatively induced Lorentz and CPT violation in QED at finite temperature
We obtain the induced Lorentz-and CPT-violating term in QED at finite temperature using imaginary-time formalism and dimensional regularization. Its form resembles a Chern-Simons-like structure, but, unexpectedly, it does not depend on the temporal component of the fixed b µ constant vector that is coupled to the axial current. Nevertheless Ward identities are respected and its coefficient vani...

We study dynamical symmetry breaking in three-dimensional QED with a Chern-Simons (CS) term, considering the screening e ect ofN avor fermions. We nd a new phase of the vacuum, in which both the fermion mass and a magnetic eld are dynamically generated, when the coe cient of the CS term equals Ne=4 . The resultant vacuum becomes the nite-density state halflled by fermions. For = Ne=2 , we nd th...

We study dynamical symmetry breaking in three-dimensional QED with a Chern-Simons (CS) term, considering the screening effect ofN flavor fermions. We find a new phase of the vacuum, in which both the fermion mass and a magnetic field are dynamically generated, when the coefficient of the CS term κ equals Ne/4π. The resultant vacuum becomes the finite-density state halffilled by fermions. For κ ...
متن کامل2 00 1 Chern - Simons action in noncommutative space
We derive the noncommutative Chern-Simons action induced by Dirac fermions coupled to a background gauge field, for the fundamental , antifundamental, and the adjoint representation. We discuss properties of the noncommutative Chern-Simons action showing in particular that the Seiberg-Witten formula maps it into the standard commutative Chern-Simons action. Recent results in noncommutative geom...
