We heal the cosmological constant problem by means of a cancellation mechanism that
adopts a phase transition during which quantum fluctuations are eliminated. To this purpose …

In this paper, we introduce a scale-independent energy-momentum squared gravity (EMSG)
that allows different gravitational couplings for different types of sources, which may lead to …

In this study, we first establish that gravity models incorporating matter-related terms, such as
f (L m), f (g μ ν T μ ν), and f (T μ ν T μ ν), into the usual matter Lagrangian density L m, are …

We consider cosmological models in which Dark Matter (DM) and Dark Energy (DE) are
described by a single component, dubbed Unified Dark Matter (UDM) models, in which the …

In the present work, we try to build up an observationally feasible cosmological model within
the framework of generalized Einstein–Aether gravity using the non-canonical scalar field …

We explore the shifted f (R)(∝ R 1+ δ) model with δ as a distinguishing physical parameter
for the study of constraints at local scales. The corresponding dynamics confronted with …

The main aim of this study is to reveal curved space and particle physics effects on the
formation of Bose-Einstein condensate (BEC) scalar fields in cosmology and around a black …

We investigate the quantum modified cosmological dynamical equations in a Friedmann–
Lemaître–Robertson–Walker universe filled with a barotropic fluid and a general non …

We revisit inflation with non-canonical scalar fields by applying deformed-steepness
exponential potentials. We show that the resulting scenario can lead to inflationary …

The unified dark fluid model unifies dark matter and dark energy into a single component,
providing an alternative and more concise framework for interpreting cosmological …
