"Study of Superconductivities in Polycyclic Aromatic Hydrocarbon"

ABSTRACT 

In this talk, I report our progress in studies of polycyclic aromatic hydrocarbon (PAH) superconductors. They might provide route to high Tc superconductors and give hints on novel pairing mechanisms. We carry out extensive numerical and experimental investigations on PAH starting from single benzene ring to phenanthrene (C14H10, three benzene rings), dibenzopentacene picene (C22H14, five benzene rings), coronene (C24H12, six benzene rings), and C30H18, seven benzene rings). Their structures, magnetic and superconducting properties as functions of doing and pressure are examined. Our results demonstrate that (1) there exists a unique superconducting phase in all PAH; (2) the spin polarized ground state is realized for charged molecules in the physical parameter regions; and (3) electron correlation is playing an important role in these compounds
