Electric conductivity in graphene: Kubo model versus a nonlocal quantum field theory model
Pablo Rodriguez-Lopez, Jian-Sheng Wang, Mauro Antezza
We compare three models of graphene electric conductivity: a non-local Kubo model, a local model derived by Falkovsky, and finally, a non-local quantum field theory (QFT) polarizat…

Beyond the Drude model: surface and non-local effects in near-field radiative heat transfer and the Casimir puzzle
Jian-Sheng Wang
We study the charge and current response functions and in a semi-infinite metal block using the electron surface Green's functions. The surface electrons behave similarly…
