Abstract
We clearly show that the symplectic structures deformations lead, upon quantization, to quantum theories of noncommutative fields. Two variants of deformations are considered. The quantization is performed and the modes expansions of the quantum fields are derived. The Hamiltonians are given and the degeneracies lifting induced by the deformation is also discussed. As an illustration, we consider the noncommutative chiral boson fields in the context of fractional quantum Hall effect. A generalized fractional filling factor is derived and shown to reproduce the Jain Hall states. We also show that the coupling of left and right edge excitations of a quantum Hall sample, gives rise a noncommutative chiral boson theory. The coupling or the noncommutativity induces a shift of the chiral components velocities. A nonlinear dispersion relation is obtained, corroborating some recent analytical and numerical analysis.
