Static, spherically symmetric solutions in -gravity and in nonmetricity scalar-tensor theory
Nikolaos Dimakis, Petros A. Terzis, Andronikos Paliathanasis +1
We solve the gravitational field equations for a static, spherically symmetric spacetime within the framework of the symmetric teleparallel theory of gravity. Specifically, we deri…
Time-covariant Schrödinger equation and invariant decay probability: The -Kantowski-Sachs universe
Theodoros Pailas, N. Dimakis, Petros A. Terzis +1
The system under study is the -Kantowski-Sachs universe. Its canonical quantization is provided based on a recently developed method: the singular minisuperspace Lagrangian desc…
Quantization of Einstein-aether Scalar field Cosmology
N. Dimakis, T. Pailas, A. Paliathanasis +3
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 inflation…
Infinite dimensional symmetry groups of the Friedmann equations
T. Pailas, N. Dimakis, Andronikos Paliathanasis +2
We find the symmetry generators for the Friedman equations emanating from a perfect fluid source, in the presence of a cosmological constant term. The relevant dynamics is seen to…
Exact solutions of Einstein-aether gravity in Bianchi Type V Cosmology
M. Roumeliotis, A. Paliathanasis, Petros A. Terzis +1
We present the solution space of the field equations in the Einstein-aether theory for the case of a vacuum Bianchi Type V space-time. We also find that there are portions of the i…
Cosmological Solutions in Multiscalar Field Theory
N. Dimakis, A. Paliathanasis, Petros A. Terzis +1
We consider a cosmological model with two scalar fields minimally coupled to gravity which have a mixed kinetic term. Hence, Chiral cosmology is included in our analysis. The coupl…
