The topology of line nodes Band structure degeneracies in topological materials can take
the form of lines or even chains of interconnected loops. Wu et al. study theoretically these …

Control of the phase transition from topological to normal insulators can allow for an on/off
switching of spin current. While topological phase transitions have been realized by …

A quantum spin Hall (QSH) insulator hosts topological states at the one-dimensional (1D)
edge, along which backscattering by nonmagnetic impurities is strictly prohibited. Its 3D …

Strain engineering is demonstrated to effectively regulate the functionality of materials, such
