We compute the full spectrum and eigenstates of the Kalb–Ramond field in a warped non-compact Randall–Sundrum-type five-dimensional spacetime in which the ordinary four-dimensional braneworld is represented by a sine-Gordon soliton. This 3-brane solution is fully consistent with both the warped gravitational field and bulk dilaton configurations. In such a background we embed a bulk antisymmetric tensor field and obtain, after reduction, an infinite tower of normalizable Kaluza–Klein massive… 
Kalb–Ramond field localization on a thick de Sitter brane
In this paper, we explore the localization condition of Kalb–Ramond (KR) tensorial gauge field on a thick de Sitter (dS) brane. Following the localization mechanism in the work by Chumbes et al (2012
Kalb–Ramond field localization in sine-Gordon braneworld models
In this paper, we investigate Kalb–Ramond field localization in two types of five-dimensional braneworld models given by sine-Gordon potentials. The sine-Gordon (SG) and double sine-Gordon (DSG)
Resonances of Kalb-Ramond field on symmetric and asymmetric thick branes
In this paper, we investigate the localization of the Kalb-Ramond field on symmetric and asymmetric thick branes, which are generated by a background scalar field. In order to localize the
Gauge Field Localization on Deformed Branes
In this paper, we utilise the Chumbes-Holf da Silva-Hott (CHH) mechanism to investigate the issue of gauge field localization on a deformed brane constructed with one scalar field, which can be
Fermion localization on branes with non-standard kinetic terms
In this paper, by using the Yukawa coupling mechanism, we consider the fermion localization in two types of braneworld models driven by real scalar fields with non-standard dynamics. Because of the
Fermion and graviton in Dirac–Born–Infeld braneworld models
In this paper, we study the braneworld models with non-standard kinetic term of Dirac–Born–Infeld (DBI) type in two case which are (I) in usual gravity and (II) in f ( T ) gravity. In each of these
Localization and mass spectra of various matter fields on scalar-tensor brane
Recently, a new scalar-tensor braneworld model was presented in [Phys. Rev. D 86 (2012) 127502]. It not only solves the gauge hierarchy problem but also reproduces a correct Friedmann-like equation
Introduction to Extra Dimensions and Thick Braneworlds
In this review, we give a brief introduction on the aspects of some extra dimension models and the five-dimensional thick brane models in extended theories of gravity. First, we briey introduce the
Spectrum structure of a fermion on Bloch branes with two scalar–fermion couplings
It is known that the Bloch brane is generated by an odd scalar field and an even one χ. In order to localize a bulk fermion on the Bloch brane, the coupling between the fermion and scalars should be


Exact solutions for a Maxwell-Kalb-Ramond action with dilaton: Localization of massless and massive modes in a sine-Gordon brane-world
We analytically find the exact propagation modes of the electromagnetic and the Kalb-Ramond fields together in a five-dimensional curved space-time. The existence and localization of gauge particles
Confluent Heun functions in gauge theories on thick braneworlds
We investigate the propagation modes of gauge fields in an infinite Randall-Sundrum scenario. In this model a sine-Gordon soliton represents our thick four-dimensional braneworld while an

We make an analysis about several aspects of localization of the Kalb-Ramond gauge field in a specific four-dimensional AdS membrane embedded in a five-dimensional space-time. The membrane is
Gravity in the randall-sundrum brane world
The weak gravitational field created by isolated matter sources in the Randall-Sundrum brane world is discussed and the leading Kaluza-Klein corrections to the linearized gravitational field of a nonrelativistic spherical object is calculated.

In this paper, we investigate the localization and the mass spectra of gravity and various bulk matter fields on a thick anti-de Sitter (AdS) brane, by presenting the mass-independent potentials of
Domain-wall branes in Lifshitz theories
We analyze whether or not Lifshitz field theories in 4 + 1 dimensions may provide ultraviolet-complete domain-wall-brane models. We first show that Lifshitz scalar-field theory can admit
Vacuum fluctuations in axion-dilaton cosmologies
We study axion-dilaton cosmologies derived from the low-energy string effective action. We present the classical homogeneous Friedmann-Robertson-Walker solutions and derive the semiclassical
