Query: Theory of the Casimir effect for graphene at finite temperature   Theory of the Casimir effect for a flat graphene layer interacting with a
parallel flat material is presented in detail. The high-temperature asymptotics
of a free energy in a graphene-metal system coincides with a Drude
high-temperature asymptotics of the metal-metal system. High-temperature
behavior in the graphene-metal system is expected at separations of the order
of 100 nm at temperature T=300K.
