英文摘要: Based on the features of chiral susceptibility and thermal susceptibility at finite temperature, the nature of chiral phase transition around the critical number of fermion flavors (N-c) and the critical temperature (T-c) at a fixed fermion flavors number in massless QED(3) is investigated. It is showed that, at finite temperature, the system exhibits a second-order phase transition at N-c or T-c and each of the estimated critical exponents is less than 1, while it reveals a higher-order continuous phase transition around N-c at zero temperature.
