摘要：

In this work we study the bound states of electrons and holes to disclinations in the framework of the theory of defects/three-dimensional gravity of Katanaev and Volovich. We find that positive disclinations repel both electrons and holes while negative disclinations act as attractors to both, giving rise to bound states. We compute the wavefunctions and the eigenvalues for these bound states.
