A Rigorous Formalism of Unconventional Symmetry Breaking in Fermi Liquid Theory and Its Application to Nematicity in FeSe
Rina Tazai, Shun Matsubara, Youichi Yamakawa +2
Unconventional symmetry breaking due to nonlocal order parameters has attracted considerable attention in many strongly correlated metals. Famous examples are the nematic order in…
Emergence of -wave superconducting state at the edge of -wave superconductors mediated by Andreev-bound-state-driven ferromagnetic fluctuations
Shun Matsubara, Hiroshi Kontani
We propose a mechanism of spin-triplet superconductivity at the edge of -wave superconductors. Recent theoretical research in -wave superconductors predicted that strong ferr…
Emergence of strongly correlated electronic states driven by the Andreev bound state in d-wave superconductors
Shun Matsubara, Hiroshi Kontani
As the surface Andreev bound state (ABS) forms at the open () edge of a -wave superconductor, the local density of states (LDOS) increases. Therefore, a strong el…
Edge-induced strongly correlated electronic states in two-dimensional Hubbard model: Enhancement of magnetic correlations and self-energy effects
Shun Matsubara, Youichi Yamakawa, Hiroshi Kontani
To understand nontrivial edge electronic states in strongly-correlated metals such as cuprate superconductors, we study the two-dimensional Hubbard models with open edge boundary.…
