Cosmological sudden singularities in gravity
Tiago B. Gonçalves, João Luís Rosa, Francisco S. N. Lobo
In this work, we study the possibility of finite-time future cosmological singularities appearing in gravity, where is the Ricci scalar and is the trace of the str…
Impact of compactlike and asymmetric configurations of thick branes on the scalar-tensor representation of gravity
João Luís Rosa, A. S. Lobão, D. Bazeia
In this work we study braneworld models in generalized gravity theories where the action depends on a function of the Ricci scalar and the trace of the stre…
Double gravitational layer traversable wormholes in hybrid metric-Palatini gravity
João Luís Rosa
In this work, we explore the existence of traversable wormhole solutions supported by double gravitational layer thin-shells and satisfying the Null Energy Condition (NEC) througho…
Sudden singularities in generalized hybrid metric-Palatini cosmologies
João Luís Rosa, Francisco S. N. Lobo, Diego Rubiera-Garcia
In this work, we explore cosmological sudden singularities arising in the dynamically equivalent scalar-tensor representation of generalized hybrid metric-Palatini gravity. Using a…
Novel modified gravity braneworld configurations with a Lagrange multiplier
Dionisio Bazeia, Douglas A. Ferreira, Francisco S. N. Lobo +1
In this work we deal with thick brane solutions in the warped five-dimensional braneworld scenario with a single extra spatial dimension of infinite extent, for a class of modified…
Thick brane structures in generalized hybrid metric-Palatini gravity
João Luís Rosa, Douglas A. Ferreira, Dionisio Bazeia +1
In this work, we study 5-dimensional braneworld scenarios in the scalar-tensor representation of the generalized hybrid metric-Palatini gravitational theory. We start by considerin…
