Distributed Topological Charge and Spinorial Holonomy in Yukawa-Regularized Graphene Disclinations
A. M. de M. Carvalho, G. Q. Garcia, E. Brito +1
Conical geometries provide the standard description of disclinations, but they concentrate the curvature at a singular apex. We introduce a Yukawa-type regularization that replaces…

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…
