Longitudinal and transverse relativity of spacetime locality in Planck-scale-deformed phase spaces
Niccol\'o Loret, Leonardo Barcaroli, Giacomo Rosati
TL;DR
This paper explores how the concept of spacetime locality varies in different reference frames within Planck-scale-deformed phase spaces, highlighting the relativity of locality at quantum gravity scales.
Contribution
It provides a comprehensive summary and new characterizations of the relativity of spacetime locality in Planck-scale-deformed phase spaces, extending previous results.
Findings
Relativity of spacetime locality depends on the observer's frame.
Different phase-space descriptions reveal complementary aspects of locality.
Results have implications for quantum gravity and Planck-scale physics.
Abstract
We summarize some of the results we obtained in arXiv:1006.2126 (Physical Review Letters 106, 071301), arXiv:1102.4637 (Physics Letters B 700, 150-156) and in arXiv:1107.3334, giving complementary characterizations of the relativity of spacetime locality that affects certain Planck-scale-deformed phase-space descriptions of free particles.
