Embolic aspects of black hole entropy
Nikolaos Kalogeropoulos
We attempt to provide a mesoscopic treatment of the origin of black hole entropy in (3+1)-dimensional spacetimes. We treat the case of horizons having space-like sections which…
Atomistic potential for graphene and other sp carbon systems
Zacharias G. Fthenakis, George Kalosakas, Georgios D. Chatzidakis +3
We introduce a torsional force field for sp carbon to augment an in-plane atomistic potential of a previous work (Kalosakas et al, J. Appl. Phys. {\bf 113}, 134307 (2013)) so t…
Electronic and gap properties of Sb and Bi based halide perovskites: An ab-initio study
A. Koliogiorgos, S. Baskoutas, I. Galanakis
Halide perovskites are currently under intense investigation due to their potential applications in optoelectronics and solar cells. Among them several crystallize in low symmetry…
Biconservative ideal hypersurfaces in Euclidean spaces
Deepika, Andreas Arvanitoyeorgos
A biconservative submanifold of a Riemannian manifold is a sub- manifold with divergence free stress-energy tensor with respect to bienergy. These are generalizations of biharamoni…
Optimization free measures of quantum resources
Nikolaos K. Kollas
A closed expression is derived for the amount of resource present in a quantum state as quantified by a distance measure based on the \emph{Tsallis relative entropy} introduced rec…
Self-referential basis of undecidable dynamics: from The Liar Paradox and The Halting Problem to The Edge of Chaos
Mikhail Prokopenko, Michael Harré, Joseph Lizier +3
In this paper we explore several fundamental relations between formal systems, algorithms, and dynamical systems, focussing on the roles of undecidability, universality, diagonaliz…
