(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…

Discrete spectrum of the quantum Reissner - Nordström geometry

N. Dimakis, A. Karagiorgos, T. Pailas +2

We start from a static, spherically symmetric space-time in the presence of an electrostatic field and construct the mini-superspace Lagrangian that reproduces the well known Reiss…

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…
