摘要: transition in Ce, this model yields a rich and unexpected phase diagram which is of intrinsicinterest. Specifically, above critical value the electron-phonon interaction, first-order with twocoexisting phases develops temperature-hybridization plane, terminates at second-order criticalpoint. The coexisting display familiar Kondo screened local-moment character, yet they alsoexhibit pronounced polaronic bipolaronic properties, respectively.DOI: 10.1103/PhysRevB.87.121102 PACS number(s): 71
