Microcausality of scalar field on noncommutative spacetime
We analyze the microcausality of free scalar field on noncommutative spacetime. To adopt the usual Lorentz invariant spectral measure, through the result of the expectation values of the Moyal commutators, for the quadratic operators such as φ(x) ⋆ φ(x), π(x, t) ⋆ π(x, t), ∂iφ(x, t) ⋆ ∂iφ(x, t), and ∂iφ(x, t) ⋆ π(x, t), we obtain that for the case θ = 0 of the spacetime noncommutativity, the mi...
متن کاملFailure of Microcausality in Quantum Field Theory on Noncommutative Spacetime
The star commutator of : φ(x)⋆φ(x) : with : φ(y)⋆φ(y) : fails to vanish at equal times and thus also fails to obey microcausality at spacelike separation even for the case in which θ0i = 0. The failure to obey microcausality for this sample observable implies that this form of noncommutative field theory fails to obey microcausality in general. This result also holds for general fields and obse...
متن کاملA New Approach to Scalar Field Theory on Noncommutative Space
A new approach to constructing the noncommutative scalar field theory is presented. Not only between x̂i and p̂j, we impose commutation relations between x̂is as well as p̂js, and give a new representation of x̂i, p̂js. We carry out both firstand second-quantization explicitly. The second-quantization is performed in both the operator formalism and the functional integral one. e-mail: [email protected]...
متن کاملMicrocausality of Dirac field on noncommutative spacetime
We study the microcausality of free Dirac field on noncommutative spacetime. We calculate the vacuum and non-vacuum state expectation values for the Moyal commutator [ψα(x) ⋆ ψβ(x), ψσ(x ) ⋆ ψτ (x )]⋆ of Dirac field on noncommutative spacetime. We find that they do not vanish for some cases of the indexes for an arbitrary spacelike interval, no matter whether θ = 0 or θ 6= 0. However for the ph...
متن کاملQuantum Gravity, Field Theory and Signatures of Noncommutative Spacetime
A pedagogical introduction to some of the main ideas and results of field theories on quantized spacetimes is presented, with emphasis on what such field theories may teach us about the problem of quantizing gravity. We examine to what extent noncommutative gauge theories may be regarded as gauge theories of gravity. UV/IR mixing is explained in detail and we describe its relations to renormali...
