Microcausality 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 کاملThe breakdown of microcausality of Dirac field on noncommutative spacetime
We analyze 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 an arbitrary spacelike interval, no matter whether θ0i = 0 or θ0i 6= 0. Therefore microcausality is violated for D...
متن کاملQuantum Mechanics of Yano tensors: Dirac equation in curved spacetime
In spacetimes admitting Yano tensors the classical theory of the spinning particle possesses enhanced worldline supersymmetry. Quantum mechanically generators of extra supersymmetries correspond to operators that in the classical limit commute with the Dirac operator and generate conserved quantities. We show that the result is preserved in the full quantum theory, that is, Yano symmetries are ...
متن کاملNew quantum numbers for the Dirac equation in curved spacetime
We show that, on spacetimes which admit Yano tensors, it is possible to construct operators that (anti)commute with the Dirac operator, thus providing extra quantum numbers even when isometries are not present. This is the main result obtained and is valid for Yano tensors of arbitrary rank. It implies that the theory of the spinning particle in such spacetimes has no anomalies and admits genui...
متن کاملStrings in Noncommutative Spacetime
Free bosonic strings in noncommutative spacetime are investigated. The string spectrum is obtained in terms of light-cone quantization. We construct two different models. In the first model the critical dimension is still required to be 26 while only extreme high energy spectrum is modified by noncommutative effect. In the second model, however, the critical dimension is reduced to be less than...
