Analytic and numeric computation of edge states and conductivity of a Kane-Mele nanoribbon

22 May 2019 Sinha Priyanka Ganguly Sudin Basu Saurabh

We compute analytic expressions for the edge states in a zigzag Kane-Mele nanoribbon (KMNR) by solving the eigenvalue equations in presence of intrinsic and Rashba spin-orbit couplings. Owing to the P-T symmetry of the Hamiltonian the edge states are protected by topological invariance and hence are found to be robust... (read more)
