Two-Dimensional Time-Reversal-Invariant Topological Insulators via Fredholm Theory
Eli Fonseca, Jacob Shapiro, Ahmed Sheta +2
We study spinful non-interacting electrons moving in two-dimensional materials which exhibit a spectral gap about the Fermi energy as well as time-reversal invariance. Using Fredho…
