Spin-Hall Insulator
Recent theories predict dissipationless spin current induced by an electric field in doped semiconductors. Nevertheless, the charge current is still dissipative in these systems...

We propose models of two dimensional paramagnetic semiconductors where the\nintrinsic spin Hall effect is exactly quantized in integer units of a\ntopological charge. The model ...
Inducing a Magnetic Monopole with Topological Surface States
Existence of the magnetic monopole is compatible with the fundamental laws of nature; however, this elusive particle has yet to be detected experimentally. We show theoretically...
Self-Doped Ti<sup>3+</sup> Enhanced Photocatalyst for Hydrogen Production under Visible Light
Through a facile one-step combustion method, partially reduced TiO(2) has been synthesized. Electron paramagnetic resonance (EPR) spectra confirm the presence of Ti(3+) in the b...

Native point defects in anatase $\mathrm{Ti}{\mathrm{O}}_{2}$ are investigated by using first-principles pseudopotential calculations based on density-functional theory (DFT). A...
General theorem relating the bulk topological number to edge states in two-dimensional insulators
We prove a general theorem on the relation between the bulk topological quantum number and the edge states in two dimensional insulators. It is shown that whenever there is a to...
