Query: Noncommutative scalar fields from symplectic deformation   This paper is concerned with the quantum theory of noncommutative scalar
fields in two dimensional space time. It is shown that the noncommutativity
originates from the the deformation of symplectic structures. The quantization
is performed and the modes expansions of the fields, in presence of an
electro-magnetic background, are derived. The Hamiltonian of the theory is
given and the degeneracies lifting, induced by the deformation, is also
discussed.
