On the Quantization of the Chern−simons Field Theory on Curved Space-times: the Coulomb Gauge Approach
نویسنده
چکیده
We consider here the Chern-Simons field theory with gauge group SU(N) in the presence of a gravitational background that describes a two-dimensional expanding “universe”. Two special cases are treated here in detail: the spatially flat Robertson-Walker space-time and the conformally static space-times having a general closed and orientable Riemann surface as spatial section. The propagator and the vertices are explicitely computed at the lowest order in perturbation theory imposing the Coulomb gauge fixing.

Chern–simons Field Theories in the Coulomb Gauge
In this talk some recent results in the quantization of Chern-Simons field theories in the Coulomb gauge will be presented. In the first part, the consistency of the Chern–Simons field theories in this gauge is proven using the Dirac’s canonical formalism for constrained systems. Despite the presence of non-trivial selfinteractions in the gauge fixed functional, it will be shown that the commut...
متن کاملEquivalence of Chern-Simons gauge theory and WZNW model using a BRST symmetry
The equivalence between the Chern-Simons gauge theory on a threedimensional manifold with boundary and theWZNWmodel on the boundary is established in a simple and general way using the BRST symmetry. Our approach is based on restoring gauge invariance of the Chern-Simons theory in the presence of a boundary. This gives a correspondence to the WZNW model that does not require solving any constra...

Chern Simons theory on a lattice and a new description of 3-manifolds invariants. Abstract A new approach to the quantization of Chern-Simons theory has been developed in recent papers [1, 2, 3, 4]. It uses a " simulation " of the mod-uli space of flat connections modulo the gauge group which reveals to be related to a lattice gauge theory based on a quantum group. After a generalization of the...

متن کاملA Non - linear σ - model for Partially Polarized QH - states
We consider a two-component quantum Hall system within a Landau-Ginzburg theory with two Chern-Simons gauge fields. From this theory we derive a sigma model covariantly coupled to one Chern-Simons field and find mean field solutions that could describe partially polarized quantum Hall states. The quasiparticles in the original model, which have quantized charge and spin, are described in the co...
