Wedge dislocation in the geometric theory of defects
TLDR
In this article, the authors consider a wedge dislocation in the framework of elasticity theory and the geometric theory of defects, and they show that the geometry theory quantitatively reproduces all the results of linear approximation in the linear approximation.Abstract:
We consider a wedge dislocation in the framework of elasticity theory and the geometric theory of defects. We show that the geometric theory quantitatively reproduces all the results of elasticity theory in the linear approximation. The coincidence is achieved by introducing a postulate that the vielbein satisfying the Einstein equations must also satisfy the gauge condition, which in the linear approximation leads to the elasticity equations for the displacement vector field. The gauge condition depends on the Poisson ratio, which can be experimentally measured. This indicates the existence of a privileged reference frame, which denies the relativity principle.read more

Geometric theory of defects
TL;DR: It is shown that the equations of asymmetric elasticity theory for Cosserat media can be naturally incorporated into the geometric theory as gauge conditions and phonon scattering on a wedge dislocation is considered.

Parallel transport of electrons in graphene parallels gravity
TL;DR: In this article, it was shown that electrons in defected graphene are transported in the same way as fundamental Dirac fermions in a nontrivial 2+ 1-dimensional space-time, with the proviso that the graphene electrons remember the lattice constant through the valley quantum numbers.

One-Dimensional Topologically Nontrivial Solutions in the Skyrme Model
TL;DR: In this paper, the Skyrme model is considered using the explicit parameterization of the rotation group through elements of its algebra, and a new class of projective models whose target spaces are arbitrary real projective spaces is proposed.

Theory of defects in solids and three-dimensional gravity
M. O. Katanaev,I.V. Volovich +1 more
TL;DR: In this paper, the authors describe the continuous distribution of dislocations and disclinations in the framework of Riemann-Cartan geometry and propose an action describing static distribution of defects, which is a combination of three-dimensional curvature and torsion squared terms.
