Mechanism of exotic density-wave and beyond-Migdal unconventional superconductivity in kagome metal AV3Sb5 (A=K, Rb, Cs)
Rina Tazai, Youichi Yamakawa, Seiichiro Onari +1
Exotic quantum phase transitions in metals, such as the nematic and smectic states, were discovered one after another and found to be universal now. The emergence of unconventional…
- 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…
Development of spin fluctuations under the presence of -wave bond order in cuprate superconductors
Satoshi Ando, Youichi Yamakawa, Seiichiro Onari +1
In cuprate superconductors, superconductivity appears below the CDW transition temperature . However, many-body electronic states under the CDW order are still far from un…
Generation of odd-frequency surface superconductivity with spontaneous spin current due to the zero-energy Andreev bound state
Shun Matsubara, Yukio Tanaka, Hiroshi Kontani
We propose that the odd-frequency wave ( wave) superconducting gap function, which is usually unstable in the bulk, naturally emerges at the edge of wave supe…
