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 ($1,1$) edge of a $d_{x^2-y^2}$-wave superconductor, the local density of states (LDOS) increases. Therefore, a strong el…
