Dynamical gap generation in 2D Dirac semimetal with deformed Dirac cone
Hai-Xiao Xiao, Jing-Rong Wang, Hong-Tao Feng +2
According to the extensive theoretical and experimental investigations, it is widely accepted that the long-range Coulomb interaction is too weak to generate a dynamical excitonic…

Calculation of the staggered spin correlation in the framework of the Dyson-Schwinger approach
Jian-Feng Li, Hong-Tao Feng, Yu Jiang +2
Based on the linear response of the fermion propagator with respect to an external field, we first derive a model-independent expression for the staggered spin susceptibility in wh…
