Topological Insulators

Topological Insulators (TIs) constitute a new quantum state of matter, in which robust metallic surface states exists inside the insulating bulk energy gap. These novel states are due to the bulk band topology induced by an intrinsic interaction in materials, the spin-orbit coupling (SOC). The energy dispersion of the topological states forms usually a Dirac cone, in which spin and momentum are lock-up with a chiral spin texture. It is remarkable that their exotic properties have been realized in real materials in recent years. TIs promise considerable application potential in multiple areas, from electronics, spintronics, and thermoelectricity to quantum computation. 

Design and predicting topological materials

We aim to realize the exotic topological properties in the real world and build a bridge between the beautiful theory of physics and experiments through realistic materials. We employ both ab-initio density-functional theory calculations and model Hamiltonian methods to investigate the electronic properties of materials. Some of our recent works are highlighted in the left menubar.
