Κ-deformed Covariant Phase Space and Quantum-gravity Uncertainty Relations
We describe the deformed covariant phase space corresponding to the so-called κ-deformation of D = 4 relativistic symmetries, with quantum “time” coordinate and Heisenberg algebra obtained according to the Heisenberg double construction. The associated modified uncertainty relations are analyzed, and in particular it is shown that these relations are consistent with independent estimates of qua...
متن کاملκ–deformed Wigner construction of relativistic wave functions and free fields on κ-Minkowski space
We describe the extension of the Wigner‘s infinite-dimensional unitary representations of Poincaré group to the case of κ-deformed Poincaré group. We show that the corresponding coordinate wave functions on noncommutative space-time are described by free field equations on κdeformed Minkowski space. The cases of Klein–Gordon, Dirac, Proca and Maxwell fields are considered. Finally some aspects ...
متن کاملLocal D = 4 Field Theory on κ – Deformed Minkowski Space ∗
We describe the local D=4 field theory on κ–deformed Minkowski space as nonlocal relativistic field theory on standard Minkowski space–time. For simplicity the case of κ-deformed scalar field φ with the interaction λφ is considered, and the κ–deformed interaction vertex is described.

متن کاملDeformed phase space and canonical quantum cosmology
The effects of noncommutativity and deformed Heisenberg algebra on the evolution of a two dimensional minisuperspace quantum cosmological model are investigated.
متن کاملκ-deformed gauge theory and θ-deformed gravity
Noncommutative (deformed, quantum) spaces are deformations of the usual commutative space-time. They depend on parameters, such that for certain values of parameters they become the usual space-time. The symmetry acting on them is given in terms of a deformed quantum group symmetry. In this work we discuss two special examples, the θ-deformed space and the κ-deformed space. In the case of the θ...
