We propose a generalization of the Chern-Simon (CS) Lagrangian which is invariant under the SIM(2) transformations but not under the full Lorentz group. We study the effect of such a term on radiation propagating over cosmological…
The role of Chern-Simons (CS) actions is reviewed, starting from the observation that all classical actions in Hamiltonian form can be viewed as 0+1 CS systems, in the same class with the coupling between the electromagnetic field and a…
We extend topologically massive electrodynamics, both by adding a higher derivative action to cast the entire three-term model in Chern-Simons (CS) form, and by embedding it in an AdS background. It can then be written as the sum of two CS…
