We have characterized the phase transitions using the autocorrelation function. Our work also reveals that the description in terms of Shannon entropy of the autocorrelation function is a clear phase transition indicator.}, organization = {This work was supported by Spanish MICINN projects FIS2011-24149 and FIS2009-08451, CEI BioTic UGR project 20F12.41 and Junta de Andalucia projects FQM-165/0207 and FQM219.}, publisher = {AIP Publishing}, keywords = {Dirac systems}, keywords = {Wave-packets}, keywords = {Fractional revivals}, keywords = {Graphene}, title = {Characterization of a quantum phase transition in Dirac systems by means of the wavepacket dynamics}, doi = {10.1063/1.4764862}, author = {Romera GutiƩrrez, Elvira and Torres, J.
