Causality and Statistics on the Groenewold - Moyal Plane
نویسندگان
چکیده
Quantum theories constructed on the noncommutative spacetime called the Groenewold-Moyal plane exhibit many interesting properties such as Lorentz and CPT noninvariance, causality violation and twisted statistics. We show that such violations lead to many striking features that may be tested experimentally. These theories predict Pauli forbidden transitions due to twisted statistics, anisotropies in the cosmic microwave background radiation due to correlations of observables in spacelike regions and Lorentz and CPT violations in scattering amplitudes.

Quantum Fields on the Groenewold - Moyal Plane 1
We give an introductory review of quantum physics on the noncommutative space-time called the Groenewold-Moyal plane. Basic ideas like star products, twisted statistics , second quantized fields and discrete symmetries are discussed. We also outline some of the recent developments in these fields and mention where one can search for experimental signals.
متن کاملThe ⋆-value Equation and Wigner Distributions in Noncommutative Heisenberg algebras∗
We consider the quantum mechanical equivalence of the Seiberg-Witten map in the context of the Weyl-Wigner-Groenewold-Moyal phase-space formalism in order to construct a quantum mechanics over noncommutative Heisenberg algebras. The formalism is then applied to the exactly soluble Landau and harmonic oscillator problems in the 2-dimensional noncommutative phase-space plane, in order to derive t...
متن کاملCommutators and propagators of Moyal star-products and microscopic causality for noncommutative scalar field theory
We study the Moyal commutators and their expectation values between vacuum states and non-vacuum states for noncommutative scalar field theory. Then from the Moyal commutators, we demonstrate that the microscopic causality is satisfied for scalar fields on noncommutative spacetime. We construct the Feynman propagator of Moyal star-product for noncommutative scalar field theory. PACS numbers: 11...
متن کاملThe Moyal product is the matrix product
This is a short comment on the Moyal formula for deformation quantization. It is shown that the Moyal algebra of functions on the plane is canonically isomorphic to an algebra of matrices of infinite size.
متن کاملUnitary Quantum Physics with Time-Space Noncommutativity
In this work quantum physics in noncommutative spacetime is developed. It is based on the work of Doplicher et al. which allows for time-space noncommutativity. The Moyal plane is treated in detail. In the context of noncommutative quantum mechanics, some important points are explored, such as the formal construction of the theory, symmetries, causality, simultaneity and observables. The dynami...
