We extend to the Horndeski realm the irreversible thermodynamics description of gravity
previously studied in “first generation” scalar-tensor theories. We identify a subclass of …

In this work we study braneworld configurations in the scalar–tensor representation of
the\(f\left (R, T\right)\) gravity theory in the presence of a Cuscuton term in the source field …

In the context of the recently proposed first-order thermodynamics of scalar-tensor gravity,
we discuss the possibility of zero-temperature states of equilibrium other than Einstein …

In this work we study braneworld models in generalized f R, T gravity theories where the
action depends on a function of the Ricci scalar R and the trace of the stress–energy tensor …

Finding effective theories of modified gravity that can resolve cosmological singularities and
avoid other physical pathologies such as ghost and gradient instabilities has turned out to …

In this work, kinks with non-canonical kinetic energy terms are studied in a type of two-
dimensional dilaton gravity model. The linear stability issue is generally discussed for …

Analytical solutions of nonminimally coupled scalar field cosmology corresponding to critical
scalar field values constitute a potential challenge to the recent first-order thermodynamics …

This work deals with thick branes in bulk with a single extra dimension modeled by a two-
field configuration. We first consider the inclusion of the cuscuton to also control the …

In this work, we investigate probe scalar field models preserving covariance on fixed, static
background geometries that present hyperscaling violation properties. We develop a first …

This work deals with braneworld models in the presence of scalar fields in a five-
dimensional warped geometry with a single extra dimension of infinite extent. We consider …
