Brillouin zone folding method for quasiperiodic superconductivity in multilayer systems: application to electronic structure and optical responses

Mao Yoshii, Sota Kitamura, Takahiro Morimoto

We construct an efficient momentum space approach to the superconductivity in quasiperiodic multilayer systems. To this end, we extend the Brillouin zone (BZ) folding method to the…
