Metal-insulator transition in a boundary three chain model
Niels John, Yuval Gefen, Bernd Rosenow
We study the boundary physics of bulk insulators by considering three coupled Hubbard chains in a linear confining potential. In the Hartree-Fock approximation, the ground state at…

Robustness of Helical Edge States Under Edge Reconstruction
Niels John, Adrian Del Maestro, Bernd Rosenow
The helical edge states of time-reversal invariant two-dimensional topological insulators are protected against backscattering in idealized models. In more realistic scenarios with…
