The nonlinearity of helical springs: An energy-based approach
Saša Ilijić, Ana Babić, Dora Ivrlač +1
A general expression for the elastic potential energy of a helical spring is derived using the basic concepts of elasticity theory and geometry. Both the translational and the rota…
An analysis of Born-Infeld boson compact objects
Andrew DeBenedictis, Sasa Ilijic
In this paper we study gravitationally bound compact objects sourced by a string theory inspired Born-Infeld scalar field. Unlike many of their canonical scalar field counterparts,…
On a Class of Exact Arbitrarily Differentiable de Sitter Cores with Kerr Exteriors: Possible gravastar or regular black hole mimickers
Sasa Ilijic, Andrew DeBenedictis
Within the paradigm of non-perturbative Einstein gravity we study continuous curvature manifolds which possess de Sitter interiors and Kerr exteriors. These manifolds could represe…
Energy condition respecting warp drives: The role of spin in Einstein-Cartan theory
Andrew DeBenedictis, Sasa Ilijic
In this paper we study the so called "warp drive" spacetimes within the Riemann-Cartan manifolds of Einstein-Cartan theory. Specifically, the role that spin may play with r…
Compact stars in extended theory of gravity
Sasa Ilijic, Marko Sossich
We consider static spherically symmetric self-gravitating configurations of the perfect fluid within the framework of the torsion-based extended theory of gravity. In particular, w…
Regular solutions in -Yang-Mills theory
Andrew DeBenedictis, Sasa Ilijic
We consider extended covariant teleparallel gravity whose action is analytic in the torsion scalar and which is sourced by an valued Yang-Mills field. Specifically…
