Complete factorization of equations of motion for generalized scalar field theories
D. Bazeia, Diego R. Granado, Elisama E. M. Lima
We demonstrate that the complete factorization of equations of motion into first-order differential equations can be obtained for real and complex scalar field theories with non-ca…
Spin-to-Charge Conversion in 2D Electron Gas and Single-layer Graphene Devices
J. G. G. S. Ramos, T. C. Vasconcelos, A. L. R. Barbosa
We investigate the spin-to-charge conversion emerging from a mesoscopic device connected to multiple terminals. We obtain analytical expressions to the characteristic coefficient o…
Lepton Flavor Violation Induced by Dark Matter
Giorgio Arcadi, C. P. Ferreira, Florian Goertz +3
Guided by gauge principles we discuss a predictive and falsifiable UV complete model where the Dirac fermion that accounts for the cold dark matter abundance in our universe induce…
The optimal multilinear Bohnenblust-Hille constants: a computational solution for the real case
F. V. Costa Júnior
The Bohnenblust-Hille inequality for -linear forms was proven in 1931 as a generalization of the famous 4/3-Littlewood inequality. The optimal constants (or at least their asymp…
A Newtonian approach to the study of irreversibility in many-body systems
Bertúlio de Lima Bernardo
Irreversibility remains one of the least understood concepts in physics. One of the main reasons is the fact that the fundamental laws of classical and quantum physics are time sym…
Scalar QNMs for higher dimensional black holes surrounded by quintessence in Rastall gravity
J. P. Morais Graça, Iarley P. Lobo
The spacetime solution for a black hole, surrounded by an exotic matter field, in Rastall gravity, is calculated in an arbitrary d-dimensional spacetime. After this, we calculate t…
Searching for Secluded Dark Matter with H.E.S.S., Fermi-LAT, and Planck
Stefano Profumo, Farinaldo S. Queiroz, Joseph Silk +1
Short-lived mediators are often used to describe dark matter interactions with Standard Model particles. When the dark matter mass is heavier than the mass of the mediator, it may…
Scattering of kinks in a non-polynomial model
Dionisio Bazeia, Ekaterina Belendryasova, Vakhid A. Gani
We study a model described by a single real scalar field in the two-dimensional space-time. The model is specified by a potential which is non-polynomial and supports analytical ki…
Hamming distance and mobility behavior in generalized rock-paper-scissors models
D. Bazeia, J. Menezes, B. F. de Oliveira +1
This work reports on two related investigations of stochastic simulations which are widely used to study biodiversity and other related issues. We first deal with the behavior of t…
Entanglement Distribution Statistic in Andreev Billiards
J. G. G. S. Ramos, A. F. Macedo-Junior, A. L. R. Barbosa
We investigate statistical aspects of the entanglement production for open chaotic mesoscopic billiards in contact with superconducting parts, known as Andreev billiards. The compl…
Thermal Casimir effect in Kerr spacetime with quintessence and massive gravitons
V. B. Bezerra, H. R. Christiansen, M. S. Cunha +2
Starting from an analytical expression for the Helmholtz free energy we calculate the thermal corrections to the Casimir energy-density and entropy within nearby ideal parallel pla…
On the stabilization of a hyperbolic Stokes system under geometric control condition
Felipe W. Chaves-Silva, Chenmin Sun
In this paper, we study the stabilization problem for a hyperbolic type Stokes system posed on a bounded domain. We show that when the damping effects are restricted to a subdomain…
Collider Detection of Dark Matter Electromagnetic Anapole Moments
Alexandre Alves, A. C. O. Santos, Kuver Sinha
Dark matter that interacts with the Standard Model by exchanging photons through higher multipole interactions occurs in a wide range of both strongly as well as weakly coupled hid…
One-loop effective potential in the non-local supersymmetric gauge theory
F. S. Gama, J. R. Nascimento, A. Yu. Petrov +1
Using the superfield formalism, we propose a non-local extension of the supersymmetric gauge theory coupled to massless chiral matter. Two different non-local models are considered…
CMB constraints on -exponential inflationary models
M. A. Santos, M. Benetti, J. S. Alcaniz +2
We analyze a class of generalized inflationary models proposed in Ref. [1], known as -exponential inflation. We show that this kind of potential can arise in the context of bran…
Asymptotic estimates for unimodular multilinear forms with small norms on sequence spaces
Nacib Gurgel Albuquerque, Lisiane Rezende
The existence of unimodular forms with small norms on sequence spaces is crucial in a variety of problems in modern analysis. We prove that the infimum of $\left\Vert A\right\Vert…
Accelerated observers and the notion of singular spacetime
Gonzalo J. Olmo, Diego Rubiera-Garcia, Antonio Sanchez-Puente
Geodesic completeness is typically regarded as a basic criterion to determine whether a given spacetime is regular or singular. However, the principle of general covariance does no…
Spatial patterns and biodiversity in off-lattice simulations of a cyclic three-species Lotka-Volterra model
P. P. Avelino, D. Bazeia, L. Losano +2
Stochastic simulations of cyclic three-species spatial predator-prey models are usually performed in square lattices with nearest neighbor interactions starting from random initial…
Scattering of kinks of the sinh-deformed model
Dionisio Bazeia, Ekaterina Belendryasova, Vakhid A. Gani
We consider the scattering of kinks of the sinh-deformed model, which is obtained from the well-known model by means of the deformation procedure. Depending on the init…
Thermodynamics of Black Holes in Rastall Gravity
Iarley P. Lobo, H. Moradpour, J. P. Morais Graça +1
A promising theory in modifying general relativity by violating the ordinary energy-momentum conservation law in curved spacetime is the Rastall theory of gravity. In this theory,…

Alexandre Rosas, Christian Van den Broeck, Katja Lindenberg
We present the stochastic thermodynamic analysis of a time-periodic single particle pump, including explicit results for flux, thermodynamic force, entropy production, work, heat a…
Nonsingular black holes, wormholes, and de Sitter cores from anisotropic fluids
C. Menchon, Gonzalo J. Olmo, D. Rubiera-Garcia
We study Born-Infeld gravity coupled to an anisotropic fluid in a static, spherically symmetric background. The free function characterizing the fluid is selected on the following…
