Observing topological edge states using moiré patterns
NUS physicists have found a new way to create and tune the topological edge states in two-dimensional (2-D) topological insulators (TIs) for potential spintronic device applications.

Topological states of matter are phases of matter that go beyond the Landau symmetry-breaking theory, which are characterized by topological invariants and topological edge states. Physicist David J. Thouless, in collaboration ...
Chemists have predicted zigzag-edged triangular graphene molecules (ZTGMs) to host ferromagnetically coupled edge states, with net spin scaling with the molecular size. Such molecules can afford large spin tunability, which ...
A team of researchers from Tohoku University, J-PARC, and Tokyo Institute of Technology conducted an in-depth study of magnetic quasiparticles called "triplons." The team conducted the study with a low-dimensional quantum ...
