Let Θ be the Wigner time reversal operator for spin half and let ϕ be a Weyl spinor. Then, for
a left-transforming ϕ, the construct ζ λ Θ ϕ∗ yields a right-transforming spinor. If instead, ϕ is …

A three-parameter (positive odd integer s, thickness factor λ, and asymmetry factor a) family
of asymmetric thick brane solutions in five dimensions were constructed from a two …

We investigate a system described by two real scalar fields coupled with gravity in (4, 1)
dimensions in warped spacetime involving one extra dimension. The results show that the …

At the beginning of the 20th century, only two physical fields were known, the
electromagnetic and gravitational ones. Einstein's theory of special relativity (SR), created in …

We deal with a scalar field coupled to gravity in five dimensions in a warped geometry. We
investigate models described by potentials that drive the system to support thick brane …

This work deals with braneworld models driven by real scalar fields with nonstandard
dynamics. We develop the first-order formalism for models with standard gravity but with the …

This work deals with braneworld scenarios in the presence of real scalar field with standard
dynamics. We show that the first-order formalism, which exists in the case of flat brane, can …

A class of thick branes in the background of sine-Gordon kinks with a scalar potential V (ϕ)=
p (1+ cos⁡ 2 ϕ q) was constructed by R. Koley and S. Kar [Classical Quantum Gravity 22 …

This work deals with cosmological models driven by real scalar field, described by standard
dynamics in generic spherical, flat, and hyperbolic geometries. We introduce a first-order …

In this work we investigate generalized theories of gravity in the so-called configurational
entropy (CE) context. We show, by means of this information-theoretical measure, that a …
