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 assumption that the aether action constants are ultra-local functions of the scalar field. For this specific theory there is a valid minisuperspace description which we use to quantize. For a particular relation between the two free functions entering…

“Time”-covariant Schrödinger equation and invariant Decay probability: The Λ-Kantowski-Sachs universe

The system under study is the Λ-Kantowski-Sachs universe. Its canonical quantization is provided based on a recently developed method: the singular minusuperspace Lagrangians describing the system,

Analytic solutions in Einstein-aether scalar field cosmology

In the context of Einstein-aether scalar field cosmology we solve the field equations and determine exact and analytic solutions. In particular, we consider a model proposed by Kanno and Soda where

Crossing the phantom divide line as an effect of quantum transitions

We consider the chiral cosmological model consisting of two scalar fields minimally coupled to gravity. In the context of a Friedmann–Lemaître–Robertson–Walker (FLRW) spacetime, and for massless

Extended analysis for the evolution of the cosmological history in Einstein-aether scalar field theory

We consider an Einstein-aether scalar field cosmological model where the aether and the scalar field are interacting. The model of our consideration consists of the two different interacting models

Dynamics of classes of barotropic fluids in spatially curved FRW spacetimes

In this article we perform dynamical analysis of a broad class of barotropic fluids in the spatially curved Friedmann-Robertson-Walker (FRW) spacetime background without considering the cosmological

Exact solutions of Einstein-æther gravity in Bianchi type V cosmology

We present the solution space of the field equations in the Einstein-æther theory for the case of a vacuum Bianchi Type V space-time. We also find that there are portions of the initial parameters

Dynamics of Einstein–Aether scalar field cosmology

We study the cosmological evolution of the field equations in the context of Einstein-Aether cosmology by including a scalar field in a spatially flat Friedmann--Lema\^itre--Robertson--Walker
