Information-theoretic analysis of dirac states in disclinated graphene quantum rings

Abstract In this paper, we study Dirac fermions confined in a graphene quantum ring with wedge disclinations under an external magnetic flux. The topological defect is modeled through a conical geometry, inducing effective gauge contributions in the angular sector of the Dirac Hamiltonian. In this case, analytical expressions for the energy spectrum are obtained under infinite-mass boundary conditions, revealing a nontrivial interplay between curvature, magnetic flux, and angular momentum quanti
