Phantom dark energy from scalartorsion coupling
Nikodem J. Popławski
We show that a scalar field without a kinetic term in the Lagrangian density, coupled to the covariant divergence of the torsion vector in the EinsteinCartan theory of gravity,…
Non-parametric reconstruction of an inflaton potential from Einstein-Cartan-Sciama-Kibble gravity with particle production
Shantanu Desai, Nikodem J. Poplawski
The coupling between spin and torsion in the Einstein-Cartan-Sciama-Kibble theory of gravity generates gravitational repulsion at very high densities, which prevents a singularity…
On the average uncertainty for systems with nonlinear coupling
Kenric P. Nelson, Sabir Umarov, Mark A. Kon
The increased uncertainty and complexity of nonlinear systems have motivated investigators to consider generalized approaches to defining an entropy function. New insights are achi…
