Low-lying excitations around a single vortex in a d-wave superconductor
Y. Morita, M. Kohmoto, K. Maki
A full quantum-mechanical treatment of the Bogoliubov-de Gennes equation for a single vortex in a d-wave superconductor is presented. First, we find low-energy states extended in f…

Near Critical States of Random Dirac Fermions
Yoshifumi Morita, Yasuhiro Hatsugai
Random Dirac fermions in a two-dimensional space are studied numerically. We realize them on a square lattice using the -flux model with random hopping. The system preserves two…
