- and -wave quantum liquid crystal orders in cuprate superconductors, -(BEDT-TTF)X, and coupled chain Hubbard models: functional-renormalization-group analysis
Rina Tazai, Youichi Yamakawa, Masahisa Tsuchiizu +1
Unconventional symmetry breaking without spin order,such as the rotational symmetry breaking (=nematic or smectic) orders as well as the spontaneous loop-current orders, have been…
Odd-parity spin-loop-current order mediated by transverse spin fluctuations in cuprates and related electron systems
Hiroshi Kontani, Youichi Yamakawa, Rina Tazai +1
Unconventional symmetry-breaking phenomena due to nontrivial order parameters attract increasing attention in strongly correlated electron systems. Here, we predict theoretically t…
Hexadecapole fluctuation mechanism for s-wave heavy fermion superconductor CeCu2Si2: Interplay between intra- and inter-orbital Cooper pairs
Rina Tazai, Hiroshi Kontani
In heavy-fermion superconductors, it is widely believed that the superconducting gap function has sign-reversal due to the strong electron correlation. However, recently discovered…
Multipole fluctuation theory for heavy fermion systems: Application to multipole orders in CeB6
Rina Tazai, Hiroshi Kontani
In heavy fermion systems, multipole degrees of freedom make possible the emergence of rich phenomena, such as hidden orders and superconductivities. However, many of them remain un…
Fully gapped s-wave superconductivity enhanced by magnetic criticality in heavy fermion system
Rina Tazai, Hiroshi Kontani
In heavy fermion systems, higher-rank multipole operators are active thanks to the strong spin-orbit interaction (SOI), and the role of diverse multipole fluctuations on the pairin…
Plain -wave superconductivity near the magnetic criticality: Enhancement of attractive electron-boson coupling vertex corrections
Rina Tazai, Youichi Yamakawa, Masahisa Tsuchiizu +1
Recent experiments revealed that the plain -wave state without any sign-reversal emerges in various metals near the magnetic criticality. To understand this counter-intuitive ph…
