Kink solutions in logarithmic scalar field theory: Excitation spectra, scattering, and decay of bions

Ekaterina Belendryasova, Vakhid A. Gani, Konstantin G. Zloshchastiev

We consider the (1+1)-dimensional Lorentz-symmetric field-theoretic model with logarithmic potential having a Mexican-hat form with two local minima similar to that of the quartic…

Superfluid vacuum theory and deformed dispersion relations

Konstantin G. Zloshchastiev

Using the logarithmic superfluid model of physical vacuum, one can formulate a quantum theory, which successfully recovers Einstein's theory of relativity in low-momenta limit, but…

Kinks in the relativistic model with logarithmic nonlinearity

Ekaterina Belendryasova, Vakhid A. Gani, Konstantin G. Zloshchastiev

We study the properties of a relativistic model with logarithmic nonlinearity. We show that such model allows two types of solutions: topologically trivial (gaussons) and topologic…

Non-Abelian Proca-Dirac-Higgs theory: particle-like solutions and their energy spectrum

Vladimir Dzhunushaliev, Vladimir Folomeev, Arislan Makhmudov

We study a system consisting of a non-Abelian SU(2) Proca field interacting with nonlinear scalar (Higgs) and spinor fields. For such a system, it is shown that particle-like solut…

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…

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--…

Integrability of the Einstein-nonlinear -model in a nontrivial topological sector

Andronikos Paliathanasis, Tim Taves, P. G. L. Leach

The integrability of the\ Einstein-nonlinear -model with nonvanishing cosmological charge is studied. We apply the method of singularity analysis of differential equ…

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…

Cosmological Einstein-Skyrme solutions with non-vanishing topological charge

Fabrizio Canfora, Andronikos Paliathanasis, Tim Taves +1

Time-dependent analytic solutions of the Einstein-Skyrme system --gravitating Skyrmions--, with topological charge one are analyzed in detail. In particular, the question of whethe…

Singularity-free model of electrically charged fermionic particles and gauged Q-balls

Vladimir Dzhunushaliev, Arislan Makhmudov, Konstantin G. Zloshchastiev

We propose a model of an electrically charged fermion as a regular localized solution of electromagnetic and spinor fields interacting with a physical vacuum, which is phenomenolog…

Collapsing sphere on the brane radiates

M Govender, N Dadhich

We study the analogue of the Oppenheimer-Snyder model of a collapsing sphere of homogeneous dust on the Randall-Sundrum type brane. We show that the collapsing sphere has the Vaidy…
