Non-local sidewall response and deviation from exact quantization of the topological magnetoelectric effect in axion-insulator thin films
Nezhat Pournaghavi, Anna Pertsova, Allan H. MacDonald +1
Topological insulator (TI) thin films with surface magnetism are expected to exhibit a quantized anomalous Hall effect (QAHE) when the magnetizations on the top and bottom surfaces…

Quantum Hall Edge States in Topological Insulator Nanoribbons
A. Pertsova, C. M. Canali, A. H. MacDonald
We present a microscopic theory of the chiral one-dimensional electron gas system localized on the sidewalls of magnetically-doped BiSe-family topological insulator nanorib…

Electric manipulation of the Mn-acceptor binding energy and the Mn-Mn exchange interaction on the GaAs (110) surface by nearby As vacancies
M. R. Mahani, A. H. MacDonald, C. M. Canali
We investigate theoretically the effect of nearby As (arsenic) vacancies on the magnetic properties of substitutional Mn (manganese) impurities on the GaAs (110) surface, using a m…
