(Compactified) black branes in four dimensional f(R)-gravity
N. Dimakis, Alex Giacomini, Andronikos Paliathanasis
A new family of analytical solutions in a four dimensional static spacetime is presented for -gravity. In contrast to General Relativity, we find that a non triv…
Analytic topologically non-trivial solutions of the (3+1)-dimensional gauged Skyrme model and extended duality
L. Avilés, F. Canfora, N. Dimakis +1
We construct the first analytic examples of topologically non-trivial solutions of the (3+1)-dimensional gauged Skyrme model within a finite box in (3+1)-dimensional flat sp…
Integrability and chemical potential in the (3+1)-dimensional Skyrme model
P. D. Alvarez, F. Canfora, N. Dimakis +1
Using a remarkable mapping from the original (3+1)dimensional Skyrme model to the Sine-Gordon model, we construct the first analytic examples of Skyrmions as well as of Skyrmions--…
Topologically non-trivial configurations in the 4d Einstein--nonlinear -model system
Fabrizio Canfora, Nikolaos Dimakis, Andronikos Paliathanasis
We construct exact, regular and topologically non-trivial\ configurations of the coupled Einstein-nonlinear sigma model in (3+1) dimensions. The ansatz for the nonlinear fi…
Noether symmetries and stability of ideal gas solution in Galileon Cosmology
N. Dimakis, Alex Giacomini, Sameerah Jamal +2
A class of generalized Galileon cosmological models, which can be described by a point-like Lagrangian, is considered in order to utilize Noether's Theorem to determine conservatio…
General Analytic Solutions of Scalar Field Cosmology with Arbitrary Potential
N. Dimakis, A. Karagiorgos, Adamantia Zampeli +3
We present the solution space for the case of a minimally coupled scalar field with arbitrary potential in a FLRW metric. This is made possible due to the existence of a nonlocal i…
