Quantum entanglement of nontrivial spacetime topology

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
We analyze the entanglement behaviors for two accelerating atoms interacting with a massless scalar field in the cosmic string spacetime. We calculate different correlation functions for different spacetime topologies. We find that entanglement behaviors

Helices in the n-dimensional Minkowski spacetime

open access: yesResults in Physics, 2019
In this work, we find position vectors of non-null helices in the n-dimensional Minkowski spacetime. We present methods to generate helices from polynomial curves.

Dynamics of quantum entanglement in de Sitter spacetime and thermal Minkowski spacetime

open access: yesNuclear Physics B, 2017
We investigate the dynamics of entanglement between two atoms in de Sitter spacetime and in thermal Minkowski spacetime. We treat the two-atom system as an open quantum system which is coupled to a conformally coupled massless scalar field in the de ...

Inquiring electromagnetic quantum fluctuations about the orientability of space

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
Orientability is an important global topological property of spacetime manifolds. It is often assumed that a test for spatial orientability requires a global journey across the whole 3-space to check for orientation-reversing paths.

Rotations in Minkowski Spacetime [PDF]

open access: yesThe Bulletin of Society for Mathematical Services and Standards, 2014
With the relation of Olinde Rodrigues-Cartan is obtained an expression for the Lorentz matrix, and it is transformed to a better form for the Newman-Penrose formalism, thus it is possible to realize rotations of the null tetrad of NP.

The Local Validity of Special Relativity, Part 1: Geometry

open access: yesPhilosophy of Physics, 2023
In this two-part essay, we distinguish several senses in which general relativity has been regarded as “locally special relativistic.” Here, in Part 1, we focus on senses in which a relativistic spacetime has been said to be “locally (approximately ...

Carrollian and celestial spaces at infinity

open access: yesJournal of High Energy Physics, 2022
We show that the geometry of the asymptotic infinities of Minkowski spacetime (in d + 1 dimensions) is captured by homogeneous spaces of the Poincaré group: the blow-ups of spatial (Spi) and timelike (Ti) infinities in the sense of Ashtekar-Hansen and a ...
