spelling Giant anharmonicity suppresses superconductivity in AlH3 under pressureRousseau, BrunoBergara, Aitor9 páginas, 2 tablas, 4 figuras.-- PACS number(s): 74.70.Ad, 63.20.Ry, 63.20.kd, 81.40.Vw.-- Trabajo presentado a la "Gordon Research Conference: Research at High Pressure" (EE.UU., 27 de junio al 2 de julio de 2010) y a "The 48th European High Pressure Research Group Conference" (Suiza, 25 al 29 de julio de 2010).The anharmonic self-energy of two zone boundary phonons were computed to lowest order for AlH3 in the Pm3̅ n structure at 110 GPa. The wave vector and branch index corresponding to these modes are situated in a region of phase space providing most of the electron-phonon coupling. The self-energies are found to be very large and the anharmonic contribution to the linewidth of one of the modes studied could be distinguished from the electron-phonon linewidth. It is found that anharmonicity suppresses the electron-phonon coupling parameter λ, providing a possible explanation for the disagreement between experiment and previous theoretical studies of superconductivity in this system.We acknowledge financial support from UPV/EHU (Grant No. IT-366-07).Peer reviewedAmerican Physical Society201220122010info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501http://hdl.handle.net/10261/44292reponame:DIGITAL.CSIC.
