 	abstract = "An increase in the number of studies involving graphene has been notable in the recent
 decades, mainly due its two-dimensional structure and also for the varied applications in technological
 devices. Superconductivity has been observed in different materials when placed under
 very-low temperatures, which motivated us to the study the different phases of the superconducting
 states in the honeycomb lattice structure of graphene.
 In this work we consider pure two-dimensional single-layer graphene on a honeycomb lattice.
 A tight-binding model of the electrons and their energy bands in the first Brillouin zone
 described by the linear dispersion of the Dirac fermions is used to describe the graphene in its
 pure form. We study the superconducting phases of the graphene using a mean field theory to
 calculate the temperature dependencies of the order parameters and also the specific heat of
 the system below the critical temperature.
 Conciling this states of matter applied to graphene and considering doping effects we analized
 the phases states for attractive electron-electron interactions energies.
 We get in addition to the usual s-wave, an exotic possibility appears in the form of a
 symmetric p+ip wave due to the symmetry structure around the Dirac points. The coexistence
 of the above two phases has been of utmost importance for our study. Hence the characteristic
 graphs of the order parameter and specific heat in the variation of the chemical potential are
 studied.",
