The exploration of the universe has recently entered a new era thanks to the multi-
messenger paradigm, characterized by a continuous increase in the quantity and quality of …

We investigate the cosmological aspects of the most general parity preserving Metric-Affine
Gravity theory quadratic in torsion and nonmetricity in the presence of a cosmological …

The covariant canonical gauge theory of gravity (CCGG) is a gauge field formulation of
gravity which a priori includes non-metricity and torsion. It extends the Lagrangian of …

An extension to the Einstein–Cartan (EC) action is discussed in terms of cosmological
solutions. The torsion incorporated in the EC Lagrangian is assumed to be totally anti …

A unification of dark matter and dark energy based on a dynamical spacetime theory is
suggested. By introducing a dynamical spacetime vector field χ μ as a Lagrange multiplier …

A model of inflation realization driven by fermions with curvature-dependent mass is studied.
Such a term is derived from the covariant canonical gauge theory of gravity (CCGG) …

First, we propose a scale-invariant modified gravity interacting with a neutral scalar inflaton
and a Higgs-like SU (2)× U (1) iso-doublet scalar field based on the formalism of non …

The cosmological implications of the covariant canonical gauge theory of gravity (CCGG)
are investigated. We deduce that, in a metric-compatible geometry, the requirement of …

We derive the interaction of fermions with a dynamical space–time based on the postulate
that the description of physics should be independent of the reference frame, which means …

Our primary objective is to construct a plausible, unified model of inflation, dark energy and
dark matter from a fundamental Lagrangian action first principle, wherein all fundamental …
