1. 1. Selfconsistent theory of superconductivity in unconventional superconductors

   Författare :Fabian Schrodi; Peter M. Oppeneer; Alex Aperis; Jörg Schmalian; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; superconductivity; unconventional; Eliashberg theory;

   Sammanfattning : Superconductivity is broadly believed to stem from either electron-phonon interaction (EPI) or from purely electronic mechanisms, such as antiferromagnetic spin fluctuations. For many materials the discussion about which of these interactions is the dominant "pairing glue" is still ongoing. LÄS MER
