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…
Analytic Studies of Static and Transport Properties of (Gauged) Skyrmions
F. Canfora, N. Dimakis, A. Paliathanasis
We study static and transport properties of Skyrmions living within a finite spatial volume in a flat (3+1)-dimensional spacetime. In particular, we derive an explicit analytic exp…
Bianchi IX cosmologies in the Einstein-Skyrme system in a sector with non-trivial topological charge
Fabrizio Canfora, Nikolaos Dimakis, Alex Giacomini +1
The dynamics of the most general Bianchi IX cosmology with three time dependent scale factors for the Einstein-Skyrme system is analyzed. For the Skyrmion, a generalized hedgehog a…
Classical and quantum analysis of 3D electromagnetic pp-wave spacetime
T. Pailas, N. Dimakis, A. Karagiorgos +3
The general classical solution of the 3D electromagnetic pp-wave spacetime has been obtained. The relevant line element contains an arbitrary essential function providing an infini…
Integrability of geodesic motions in curved manifolds through non-local conserved charges
N. Dimakis, Petros A. Terzis, T. Christodoulakis
In this work we study the general system of geodesic equations for the case of a massive particle moving on an arbitrary curved manifold. The investigation is carried out from the…
