Orbital Nematic Instability in Two-Orbital Hubbard Model: Renormalization-Group + Constrained RPA Analysis
Masahisa Tsuchiizu, Yusuke Ohno, Seiichiro Onari +1
Motivated by the nematic electronic fluid phase in Sr_{3}Ru_{2}O_{7}, we develop a combined scheme of the renormalization-group method and the random-phase-approximation-type metho…

Spin-Fluctuation-Driven Orbital Nematic Order in Ru-Oxides: Self-Consistent Vertex Correction Analysis for Two-Orbital Model
Yusuke Ohno, Masahisa Tsuchiizu, Seiichiro Onari +1
To reveal the origin of the "nematic electronic fluid phase" in SrRuO, we apply the self-consistent vertex correction analysis to the ()-orbital Hubbard…
