Elastic field causing noncommutativity
A. L. Silva Netto, A. M. de M. Carvalho, G. Q. Garcia +1
We study how a uniform torsion background, modeling a continuous density of screw dislocations and induces effective spatial noncommutativity and reshapes the energy spectrum of a…

Geometric Modeling of a Line of Alternating Disclinations: Application to Grain Boundaries in Graphene
A. M. de M. Carvalho, C. Furtado
We develop a conformal geometric model for grain boundaries in graphene based on a periodic line of alternating disclinations. Within the framework of (2+1)-dimensional gravity, we…
