Screening potential topological insulators in half-Heusler compounds via compressed-sensing

Beyond the finite training data, the proposed descriptor is employed to screen many new half-Heusler compounds, including those with integer and fractional stoichiometry, and a larger number of possible topological insulators are predicted. Expand abstract.

Finite-dimensional bistable topological insulators: From small to large

In this work using as an example realistic polariton topological insulators built from small-size honeycomb arrays of microcavity pillars, we illustrate how topological properties of the system build up upon gradual increase of its dimensionality. Expand abstract.

Type-II quadrupole topological insulators

The existence of the new topological insulating phase means that new multipole topological insulators with distinct properties can exist in broader contexts beyond classical constraints. Expand abstract.

Layered Photonic Topological Insulators

Layered photonic topological insulators not only offer a route towards the observation of richer nontrivial phases, but also open a way for device applications in integrated photonics and information processing by using the additional layer pseudospin. Expand abstract.
