报告题目:“Novel Superconductivity Induced by Electron-Phonon Interaction” 
报告摘要:Understanding exotic, non s--wave like states of Cooper pairs is important and may lead to new superconductors with higher critical temperatures and novel properties. Their existence is known to be possible but has always been thought to be associated with nontraditional mechanisms of superconductivity where electronic correlations play an important role. Here we use a first principles linear response calculation to show that in doped Bi2Se3 an unconventional p--wave like state can be favored via a conventional phonon--mediated mechanism, as driven by an unusual, almost singular behavior of the electron-phonon interaction at long wavelengths. This may provide a new platform for our understanding superconductivity phenomena in doped band insulators.
