Torsion at different scales: from materials to the Universe
The concept of torsion in geometry, although known for a long time, has not gained
considerable attention from the physics community until relatively recently, due to its diverse …

Spontaneous Lorentz symmetry-breaking constraints in Kalb-Ramond gravity
ELB Junior, JTSS Junior, FSN Lobo… - arXiv preprint arXiv …, 2024 - arxiv.org
In this work, we study timelike and lightlike geodesics in Kalb-Ramond (KR) gravity around a
black hole with the goal of constraining the Lorentz symmetry-breaking parameter $ l $. The …

[HTML][HTML] Quantizing a non-locally massive 2-form model
K Abhinav - Physics Letters B, 2024 - Elsevier
A non-local yet gauge-invariantly massive 2-form model is considered that leads to local and
unitary dynamics upon proper gauge-fixing. Since canonical momenta cannot be defined …

Antisymmetric tensor influence on charged black hole lensing phenomena and time delay
A AA Filho - arXiv preprint arXiv:2406.11582, 2024 - arxiv.org
In this work, we investigate the gravitational lensing of a charged black hole (spherically
symmetric) within the context of Lorentz violation triggered by an antisymmetric tensor field …

A Gauge-Invariant Massive 2-form Model and its Quantization
K Abhinav - arXiv preprint arXiv:2310.18272, 2023 - arxiv.org
An Abelian 2-form theory that maintains gauge-invariance despite having a mass is
considered in 3+ 1 dimensions. Though this mass owes to a non-local term the …

A mass for the dual axion
A Platschorre - arXiv preprint arXiv:2405.14931, 2024 - arxiv.org
In this article we study a modification of axion physics in which the dual axion acquires a
mass. This mass explicitly breaks the shift symmetry of the dual axion. The potential …

Antisymmetric tensor portals to dark matter
AJ Magnus, JG Fenwick, R Dick - arXiv preprint arXiv:2409.05915, 2024 - arxiv.org
Both freeze-in of very weakly coupled dark matter and freeze-out of initially thermalized dark
matter from the primordial heat bath provide interesting possibilities for dark matter creation …
