▎ 摘 要
Based on a self-consistent method, we predict theoretically that there exist intrinsic plasmarons in graphene at nonzero temperature, with a well defined mode, as shown by the result of Landau damping. We find that there are sharp differences between the discussed system and the QCD/QED system. Firstly, the thermal mass is proportional to alpha(3/4)(g) gT but not alpha T-g. Secondly, at 0 < q < q(c), the fermion channel and plasmaron channel are nearly degenerate, and furthermore the energy difference between fermion and plasmaron becomes larger and larger with increasing q in the region q > q(c). Thirdly, the fermion behaves as a 'relativistic particle' with nonzero mass, and the plasmaron exhibits an abnormal dispersion at moderate momentum.
