Correlation between optical phonon softening and superconducting in YBaCuO within -wave Eliashberg theory
Cunyuan Jiang, Giovanni A. Ummarino, Matteo Baggioli +2
We provide a mathematical description, based on d-wave Eliashberg theory, of the strong correlation between the experimentally observed softening of Raman modes associated with in-…
Constrains on s and d components of electron boson coupling constants in one band d wave Eliashberg theory for high Tc superconductors
Giovanni Alberto Ummarino
The phenomenology of overdoped high Tc superconductors can be described by a one band d wave Eliashberg theory where the mechanism of superconducting coupling is mediated by antife…
Anharmonic theory of superconductivity and its applications to emerging quantum materials
Chandan Setty, Matteo Baggioli, Alessio Zaccone
The role of anharmonicity on superconductivity has often been disregarded in the past. Recently, it has been recognized that anharmonic decoherence could play a fundamental role in…
Possible enhancement of the superconducting due to sharp Kohn-like soft phonon anomalies
Cunyuan Jiang, Enrico Beneduce, Matteo Baggioli +2
Phonon softening is a ubiquitous phenomenon in condensed matter systems which is often associated with charge density wave (CDW) instabilities and anharmonicity. The interplay betw…
