Magnetic Impurity States and Ferromagnetic Interaction in Diluted Magnetic Semiconductors
M. Ichimura, K. Tanikawa, S. Takahashi +2
The electronic structure of diluted magnetic semiconductors is studied, especially focusing on the hole character. The Haldane-Anderson model is extend to a magnetic impurity, and…

Long-range ferromagnetic correlations between Anderson impurities in a semiconductor host
N. Bulut, K. Tanikawa, S. Takahashi +1
We study the two-impurity Anderson model for a semiconductor host using the quantum Monte Carlo technique. We find that the impurity spins exhibit ferromagnetic correlations with a…

Superconducting pi qubit with a ferromagnetic Josephson junction
T. Yamashita, K. Tanikawa, S. Takahashi +1
Solid-state qubits have the potential for the large-scale integration and for the flexibility of layout for quantum computing. However, their short decoherence time due to the coup…
