Dispersion C3 coefficients for the alkali-metal atoms interacting with a graphene layer and with a carbon nanotube

Bindiya Arora, Harjeet Kaur, B. K. Sahoo

We evaluate separation dependent van der Waal dispersion ($C_3$) coefficients for the interactions of the Li, Na, K and Rb alkali atoms with a graphene layer and with a single wall…
