Quantization of Einstein-aether scalar field cosmology
European Physical Journal C: Particles and Fields, 2021 We present, for the first time, the quantization process for the Einstein-aether scalar field cosmology. We consider a cosmological theory proposed as a Lorentz violating inflationary model, where the aether and scalar fields interact through the ...

A classification of scalar field potentials with cosmological scaling solutions [PDF]
, 1998 An attractive method of obtaining an effective cosmological constant at the present epoch is through the potential energy of a scalar field. Considering models with a perfect fluid and a scalar field, we classify all potentials for which the scalar field

R2 quantum corrected scalar field inflation
Nuclear Physics B, 2022 String theory enjoys an elevated role among quantum gravity theories, since it seems to be the most consistent UV completion of general relativity and the Standard Model.

Collapse of an axion scalar field
European Physical Journal C: Particles and Fields, 2021 The manuscript deals with an interacting scalar field that mimics the evolution of the so-called axion scalar dark matter or axion like particles with ultra-light masses.

Reformulating scalar–tensor field theories as scalar–scalar field theories using a novel geometry
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2022 In this paper, I shall show how the notions of Finsler geometry can be used to construct a similar geometry using a scalar field, f , on the cotangent bundle of a differentiable manifold M . This will enable me to use the second vertical derivatives of f , along with ...

Stability of a Noncanonical Scalar Field Model during Cosmological Date
Advances in High Energy Physics, 2016 Using the noncanonical model of scalar field, the cosmological consequences of a pervasive, self-interacting, homogeneous, and rolling scalar field are studied.

Dynamical Analysis of Scalar Field Cosmologies with Spatial Curvature
The Open Journal of Astrophysics, 2016 We explore the dynamical behaviour of cosmological models involving a scalar field (with an exponential potential and a canonical kinetic term) and a matter fluid with spatial curvature included in the equations of motion.

Zeta-nonlocal scalar fields [PDF]
Theoretical and Mathematical Physics, 2008 We consider some nonlocal and nonpolynomial scalar field models originated from p-adic string theory. Infinite number of spacetime derivatives is determined by the operator valued Riemann zeta function through d'Alembertian $\Box$ in its argument. Construction of the corresponding Lagrangians L starts with the exact Lagrangian $\mathcal{L}_p$ for ...

Fractional Scalar Field Cosmology
Fractal and FractionalConsidering the Friedmann–Lemaître–Robertson–Walker (FLRW) metric and the Einstein scalar field system as an underlying gravitational model to construct fractional cosmological models has interesting implications in both classical and quantum regimes ...
