Classification of -modes for neutron stars with a strong transition: Novel universal relation including slow stable hybrid stars
M. C. Rodriguez, José C. Jiménez, Ignacio F. Ranea-Sandoval
We investigate the behavior of the non-radial gravity-pulsation discontinuity -mode in neutron stars with a strong first-order phase transition which give rise to hybrid-star co…
Kondo effect in a two-dimensional electron gas in the Persistent Spin Helix regime
T. O. Puel, M. A. Manya, G. S. Diniz +2
The Kondo effect arises from many-body interactions between localized magnetic impurities and conduction electrons, affecting electronic properties at low temperatures. In this stu…
Oscillatory properties of strange quark stars described by the vector MIT bag model
Luiz L. Lopes, Jose C. Jimenez, Luis B. Castro +1
We investigated the radial and non-radial fundamental () mode oscillations of self-bound (quark) stars obtained after employing the Vector MIT (vMIT) bag model. Within this mode…
How the QCD trace anomaly behaves at the core of twin stars?
José C. Jiménez, Lucas Lazzari, Victor P. Gonçalves
We investigate the behavior of the dense and cold (normalized) QCD trace anomaly, , in the interior of twin neutron stars (obtained from several sets of equations of state in ag…
Symmetries in the Hamiltonian formulation of string theory
Héctor A. Benítez, René Negrón
In the context of the Hamiltonian formulation of string theory, a widely acknowledged issue is the inability of the first-class constraints to accurately reproduce the Lagrangian s…
Charged scalar bosons in a Bonnor-Melvin- universe at conical approximation
Luis B. Castro, Angel E. Obispo, Andrés G. Jirón
The quantum dynamics of charged scalar bosons in a Bonnor-Melvin- universe is considered. In this study, the behavior of charged scalar bosons is explored within the framework o…
A note on hidden classes in spinor classification
R. J. Bueno Rogerio, R. T. Cavalcanti, C. H. Coronado Villalobos +1
The Lounesto classification is a well-established scheme for categorizing spinors based on their physical content, which are determined by their associated bilinear forms. It consi…
On the electromagnetic interaction and the anomalous term in the Duffin-Kemmer-Petiau theory
Andrés G. Jirón, Luis B. Castro, Antonio S. de Castro +1
The problem of vectorial mesons embedded in an electromagnetic field via Duffin-Kemmer-Petiau (DKP) formalism is reinvestigated. Considering the electromagnetic interaction as a mi…
Remarks on the ()-dimensional Duffin-Kemmer-Petiau oscillator in an external magnetic field
Andrés G. Jirón, Luis B. Castro, Angel E. Obispo +1
This work re-examines the issue of spin- particles in a ()-dimensional Duffin-Kemmer-Petiau oscillator (DKPO) in the presence of an external magnetic field. By following th…
Effect of a critical magnetic field on the control of scalar neutral boson pair production in the context of Lorentz-symmetry violation
Andrés G. Jirón, Angel E. Obispo, J. Daniel Espinoza Loayza +2
This study investigates the production of neutral scalar boson pairs in static electromagnetic fields resulting from Lorentz-symmetry violation (LSV), with a focus on the parity-ev…
Singular spinors as expansion coefficients of local spin-half fermionic and bosonic fields: On the two-fold Wigner degeneracy
R. J. Bueno Rogerio, C. H. Coronado Villalobos
By scrutinizing the singular sector of the Lounesto spinor classification, we investigate the correct definition of the expansion coefficient functions of local fermionic fields wi…
Revisiting Takahashi's inversion theorem in discrete symmetry-based dual frameworks
R. J. Bueno Rogerio, R. T. Cavalcanti, J. M. Hoff da Silva +1
The so-called Takahashi's \emph{Inversion Theorem}, the reconstruction of a given spinor based on its bilinear covariants, are re-examined, considering alternative dual structures.…
Comment on "Relativistic quantum oscillator model under the effects of the violation of Lorentz symmetry by an arbitrary fixed vector field'' by Faizuddin Ahmed
Andrés G. Jirón Vicente, Luis B. Castro, Angel E. Obispo
We obtain the correct expressions for the energy and normalized eigenfunctions for a spin-zero relativistic quantum oscillator model under the violation of Lorentz symmetry defined…
Effects of a uniform magnetic field on twisted graphene nanoribbons
Camila C. Soares, Angel E. Obispo, Andrés G. Jirón Vicente +1
In the present work, the relativistic quantum motion of massless fermions in a helicoidal graphene nanoribbon under the influence of a uniform magnetic field is investigated. Consi…
Identifying the population of stable resonant asteroids using large databases
Valerio Carruba, Safwan Aljbaae, Rita de Cassia Domingos +2
Large observational surveys, like those that will be conducted at the Vera C. Rubin Observatory, are expected to discover up to one million new asteroids in the first year of opera…
Thermoelectric properties of topological chains coupled to a quantum dot
A. C. P. Lima, R. C. Bento Ribeiro, J. H. Correa +3
Topological one-dimensional superconductors can sustain in their extremities zero energy modes that are protected by different kinds of symmetries. The observation of these excitat…
Machine Learning applied to asteroid dynamics
V. Carruba, S. Aljbaae, R. C. Domingos +2
Machine Learning (ML) is the branch of computer science that studies computer algorithms that can learn from data. It is mainly divided into supervised learning, where the computer…
