Two-sided NED black-hole, naked-singularity, and soliton solutions
The European Physical Journal CAbstract We consider non-linear electrodynamics (NED) minimally coupled to general relativity. We derive novel electrically charged, spherically symmetric, black-hole solutions having, for some set of parameters, all their NED fields (the electric field and the square of the electromagnetic field) regular for all values of the radial ...

, 2022 The study of gravitationally localised quantum states, in which quantum particles are bound together by their mutual gravitational interaction, has been a topic of considerable research for over 50 years. Stemming from John Wheeler's initial concept of an electromagnetic 'geon', focus quickly converged on scalar fields with the introduction of the ...

Bright and Singular Soliton Solutions of Tzitzéica Type Equations Appear in Nonlinear Optics
, 2019 We investigate the exact travelling wave solutions of the Tzitzéica-Dodd–Bullough–Mikhailov (TDBM) and Tzitzéica-type (TT) equations, appear in nonlinear optics, using simple ansatz approach. We use the Painlevé and traveling wave transformations to convert the mentioned nonlinear equations into ...

Thermal ScienceThis study on the negative-order fractional space-time modified KdV (nfmKdV) equation provides a comprehensive analysis of how fractional differentials affect the dynamics of solitons in non-linear wave models. We are referring to introduces the nfmKdV equation, a significant extension of the traditional KdV equation, which is commonly used
