英文摘要	At zero temperature and density, the nature of the chiral phase transition in QED(3) with N-f massless fermion flavors is investigated. To this end, in Landau gauge, we numerically solve the coupled Dyson Schwinger equations for the fermion and boson propagator within the bare and simplified Ball Chiu vertices separately. It is found that, in the bare vertex approximation, the system undergoes a high-order continuous phase transition from the Nambu-Goldstone phase into the Wigner phase when the number of fermion flavors N-f reaches the critical number N-f.c, while the system exhibits a typical characteristic of second-order phase transition for the simplified Ball-Chiu vertex.
