Induced odd-frequency superconducting state in vertex-corrected Eliashberg theory

F Schrodi, A Aperis, PM Oppeneer - Physical Review B, 2021 - APS
We show that vertex corrections to Migdal's theorem in general induce an odd-frequency
spin-triplet superconducting order parameter, which coexists with its more commonly known …

Quantitative measure of correlation strength among intertwined many-body interactions

H Iwasawa, T Ueno, Y Yoshida, H Eisaki, Y Aiura… - Physical Review …, 2023 - APS
The intertwined coupling among various many-body interactions is increasingly recognized
as playing a key role in strongly correlated electron systems. However, understanding their …

Do** dependence and multichannel mediators of superconductivity: calculations for a cuprate model

F Schrodi, A Aperis, PM Oppeneer - Electronic Structure, 2024 - iopscience.iop.org
We study two aspects of the superconductivity in a cuprate model system, its do**
dependence and the influence of competing pairing mediators. We first include electron …

Selfconsistent investigation of multichannel superconductivity in a cuprate model system

F Schrodi, A Aperis, PM Oppeneer - arxiv preprint arxiv:2110.10758, 2021 - arxiv.org
The origin of high-temperature superconductivity in cuprates is still an unresolved issue.
Among the most likely candidates for mediating the Cooper pair condensate are spin …
