Higher derivative Hořava-Lifshitz fermions: from superconductivity to atomic spectroscopy
A. A. Araújo Filho, K. E. L. de Farias, N. Heidari +2
We investigate an isotropic Hořava-Lifshitz fermion theory supplemented by a dimension-six spatial derivative operator, preserving first order time evolution while modifying the ul…
Testing Statistical Isotropy in the FRB Sky Distribution: A Selection-Function-Aware Framework
Bruno W. N. Ribeiro, Thais Lemos, Carlos A. P. Bengaly +5
We perform a test of statistical isotropy in the Universe using the sky distribution of fast radio bursts (FRBs), based on a compilation of events detected by multiple surve…
Generalist Vision-Language Models for Fast Radio Burst detection: a zero-shot benchmark against a specialized detector
Raiff H. Santos, Amilcar R. Queiroz, Tharcisyo S. S. Duarte +2
Fast Radio Burst (FRB) detection increasingly relies on specialized deep learning models that require large task-specific training sets and cannot be redefined without retraining.…
Constraints on Dark Energy and Modified Gravity Models from Fast Radio Bursts and Late-Time Geometric Probes
Bruno W. N. Ribeiro, Lázaro L. Sales, Klécio. E. L. de Farias +3
We investigate the impact of 104 localized FRBs on cosmological parameter estimation when combined with three established late-time probes: Cosmic Chronometers (CC), Type Ia Supern…
Lorentz-violating modifications to particle dynamics, thermodynamics and vacuum energy in bumblebee gravity
A. A. Araújo Filho, K. E. L. de Farias, E. Passos +5
We investigate how spontaneous Lorentz symmetry breaking in bumblebee gravity modifies particle dynamics, thermodynamics, and vacuum energy around a static black hole background. S…
Neutrino oscillations in a Kalb-Ramond black hole background
Yuxuan Shi, A. A. Araújo Filho, K. E. L. de Farias +2
The analysis examines how neutrinos behave when their trajectories unfold around a black hole sourced by a Kalb-Ramond field, where spontaneous Lorentz symmetry breaking reshapes t…
Two-dimensional Lorentz-violating Casimir effect
K. E. L. de Farias, M. A. Anacleto, F. A. Brito +2
In this study, we consider the four-dimensional Maxwell electrodynamics extended with CPT-even Myers-Pospelov Lorentz-violating dimension-six operators to investigate the associate…
Aether-Electromagnetic theory and the Casimir effect
K. E. L. de Farias, M. A. Anacleto, E. Passos +3
In this study, we explore the impact of an additional dimension, as proposed in Kaluza-Klein's theory, on the Casimir effect within the context of Lorentz invariance violation (LIV…
Scalar self-interaction in the spacetime of a cosmic dispiration
K. E. L. de Farias, E. A. F. Bragança, H. F. Santana Mota
In the present paper we investigate the classical self-interaction associated with a charged scalar point particle placed at rest in the gravitational field of a linear topological…
Radiatively induced finite and (un)determined Chern-Simons-like terms
E. Passos, K. E. L. de farias, M. A. Anacleto +2
The problem of Chern-Simons-like term induction via quantum corrections in four-dimensions is investigated in two different cases. In the first case, we consider two distinct appro…
