Some remarks on Relativistic Diffusion and the Spectral Dimension Criterion
C. R. Muniz, M. S. Cunha, R. N. Costa Filho +1
The spectral dimension for high energies is calculated using the Relativistic Schrödinger Equation Analytically Continued (RSEAC) instead of the so-called Telegraph's Equatio…
Relativistic geometric quantum phases from the Lorentz symmetry violation effects in the CPT-even gauge sector of Standard Model Extension
K. Bakke, H. Belich
We discuss the appearance of relativistic geometric quantum phases for a Dirac neutral particle based on possible scenarios of the Lorentz symmetry violation background in the CPT-…
On the influence of a Rashba-type coupling induced by Lorentz-violating effects on a Landau system for a neutral particle
K. Bakke, H. Belich
We study a possible scenario of the Lorentz symmetry violation background that allows us to build an analogue of the Landau system for a nonrelativistic Dirac neutral particle inte…

A. Mohammadi, E. R. Bezerra de Mello, A. A. Saharian
We investigate the finite temperature expectation values of the charge and current densities for a massive fermionic field with nonzero chemical potential, , in the geometry of…
On the gauge dependence of the effective potential for Horava-Lifshitz-like theories
A. M. Lima, J. R. Nascimento, A. Yu. Petrov +1
We calculate the one-loop effective potential for Horava-Lifshitz-like QED with an arbitrary critical exponent within different approaches and discuss its gauge dependence.
On the duality in CPT-even Lorentz-breaking theories
A. P. Baeta Scarpelli, J. R. Nascimento, A. Yu. Petrov +1
In this paper, we generalize the duality between self-dual and Maxwell-Chern-Simons theories for the case of a CPT-even Lorentz-breaking extension of these theories. The duality is…
Acceleration effects on atomic clocks
F. Dahia, P. J. Felix de Araujo
We consider a free massive particle inside a box which is dragged by Rindler observers. Admitting that the particle obeys the Klein-Gordon equation, we find the frequencies of the…
Crystal clear lessons on the microstructure of space-time and modified gravity
Francisco S. N. Lobo, Gonzalo J. Olmo, D. Rubiera-Garcia
We argue that a microscopic structure for space-time such as that expected in a quantum foam scenario, in which microscopic wormholes and other topological structures should play a…
Neutrino mass mechanisms in 3-3-1 models: A short review
C. A. de S. Pires
In this paper we review some mechanisms that provide light neutrinos in the framework of 3-3-1 gauge models without exotic leptons. In regard to the minimal 3-3-1 model, we call th…
New braneworld models in the presence of auxiliary fields
D. Bazeia, M. A. Marques, R. Menezes +1
We study braneworld models in the presence of auxiliary fields. We use the first-order framework to investigate several distinct possibilities, where the standard braneworld scenar…
On the Klein-Gordon oscillator subject to a Coulomb-type potential
K. Bakke, C. Furtado
By introducing the scalar potential as modification in the mass term of the Klein-Gordon equation, the influence of a Coulomb-type potential on the Klein-Gordon oscillator is inves…

Jonas R. F. Lima, F. Moraes
In this work we study theoretically the electronic properties of a sheet of graphene grown on a periodic heterostructure substrate. We write an effective Dirac equation, which incl…

We evaluate the Hadamard function and the vacuum expectation value of the current density for a massive complex scalar field in the generalized geometry of a straight cosmic string…

D. Bazeia, F. A. Brito, F. G. Costa
In this paper we have considered the structure of the non-projectable Horava-Melby-Thompson (HMT) gravity to find braneworld scenarios. A relativistic scalar field is considered in…

D. Bazeia, L. Losano, R. Menezes +2
This work deals with modified gravity in five dimensional spacetime. We study a thick Palatini brane, that is, a braneworld scenario described by an anti-de Sitter warped ge…
A path integral approach to the Langevin equation
Ashok K. Das, Sudhakar Panda, J. R. L. Santos
We study the Langevin equation with both a white noise and a colored noise. We construct the Lagrangian as well as the Hamiltonian for the generalized Langevin equation which leads…
Universal Braess paradox in open quantum dots
A. L. R. Barbosa, D. Bazeia, J. G. G. S. Ramos
We present analytical and numerical results that demonstrate the presence of the Braess paradox in chaotic quantum dots. The paradox that we identify, originally perceived in class…

F. Dahia, Alex de Albuquerque Silva
Classical tests of General Relativity in braneworld scenarios have been investigated recently with the purpose of posing observational constraints on parameters of some models of i…
