Discrete Lorentz symmetry and discrete time translational symmetry
The Lorentz symmetry and the space and time translational symmetry are fundamental symmetries of nature. Crystals are themanifestation of the continuous space translational symmetry being spontaneously broken into a discrete one.We argue that, following the space translational symmetry, the continuous Lorentz symmetry should also be broken into a discrete one, which further implies that the con...

متن کاملTesting Lorentz Symmetry in Space
Atomic clocks, masers, and other precision oscillators are likely to be placed on the International Space Station and other satellites in the future. These instruments will have the potential to measure Lorentz-violation coefficients, and in particular may provide access to parts of the Lorentz-violation coefficient space at levels not accessible with Earth-based experiments. The basic issues a...
متن کاملClock-comparison tests of Lorentz and CPT symmetry in space.
Clock-comparison experiments conducted in space can provide access to many unmeasured coefficients for Lorentz and CPT violation. The orbital configuration of a satellite platform and the relatively large velocities attainable in a deep-space mission would permit a broad range of tests with Planck-scale sensitivity.
متن کاملThe Violation of Remaining Lorentz Symmetry in the Approach of TOPT to Space-Time Noncommutativity
We study remaining Lorentz symmetry, i.e. Lorentz transformations which leave the noncommutativity parameter θ invariant, within the approach of TOPT to space-time noncommutative theories. Their violation is shown in a simple scattering process. We argue that this results from the non-covariant transformation properties of the phase factors appearing in TOPT. PACS: 11.10.Nx, 11.30.Cp
