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…
Spin dynamics of Mn impurities and their bound acceptors in GaAs
M. R. Mahani, A. Pertsova, C. M. Canali
We present results of tight-binding spin-dynamics simulations of individual and pairs of substitutional Mn impurities in GaAs. Our approach is based on the mixed quantum-classical…
Interplay between Mn-acceptor state and Dirac surface states in Mn-doped BiSe topological insulator
M. R. Mahani, A. Pertsova, M. Fhokru Islam +1
We investigate the properties of a single substitutional Mn impurity and its associated acceptor state on the (111) surface of BiSe topological insulator. Combining ab init…
Trend of the magnetic anisotropy for individual Mn dopants near the (110) GaAs surface
M R Mahani, A Pertsova, C M Canali
Using a microscopic finite-cluster tight-binding model, we investigate the trend of the magnetic anisotropy energy as a function of the cluster size for an individual Mn impurity p…
Electronic structure and magnetic properties of Mn and Fe impurities near GaAs (110) surface
M. R. Mahani, M. Fhokrul Islam, A. Pertsova +1
Combining density-functional theory calculations and microscopic tight-binding models, we investigate theoretically the electronic and magnetic properties of individual substitutio…
Time-dependent electron transport through a strongly correlated quantum dot: multiple-probe open boundary conditions approach
A. Pertsova, M. Stamenova, S. Sanvito
We present a time-dependent study of electron transport through a strongly correlated quantum dot. The time-dependent current is obtained with the multiple-probe battery method, wh…
