Abundance of $\mathbb{Z}_2$ topological order in exfoliable two-dimensional insulators

Crystallographic splitting theorem for band representations and fragile topological photonic crystals

The fundamental building blocks in band theory are band representations (BRs): bands whose infinitely-numbered Wannier functions are generated (by action of a space group) from a finite number of symmetric Wannier functions centered on a point in space. Expand abstract.

Theory of bi-linear magnetoresistance within the minimal model for surface states in topological insulators

A new mechanism of bi-linear magnetoresistance (BMR) is studied theoretically within the minimal model describing surface electronic states in topological insulators (TIs). Expand abstract.

Exciting Pseudospin Dependent Edge States in Plasmonic Metasurfaces

However, unlike the spin-momentum locking characteristic of topological insulators, these modes are not purely unidirectional and their propagation properties can be understood by analysing the spin angular momentum of the electromagnetic field, which is inhomogenous in the plane of the lattice.

Universal momentum-to-real-space mapping of topological singularities

Topological properties of materials, as manifested in the intriguing phenomena of quantum Hall effect and topological insulators, have attracted overwhelming transdisciplinary interest in recent years. Expand abstract.

Bound states in the continuum of higher-order topological insulators

Our work shows that topological bulk-boundary correspondences are immune to the existence of interfering bulk bands, expanding the search space for crystalline topological phases. Expand abstract.

Probing the minigap in topological insulator-based Josephson junctions under radio frequency irradiation

Recently, a contact-resistance-measurement method was developed to detect the minigap, hence the Andreev bound states (ABSs), in Josephson junctions constructed on the surface of three-dimensional topological insulators (3D TIs). Expand abstract.

Radiative Decay of Bound Electron Pairs in Two-Dimensional Topological Insulators

Bound electron pairs (BEPs) with energy in the band gap are interesting because they can participate in charge and spin transport in modern topologically nontrivial materials. Expand abstract.

Quantum decay in a topological continuum

Here we consider multilevel quantum decay in a bath sustaining unidirectional (chiral) propagating states, such as in quantum Hall or in Floquet topological insulators, and show that the chiral nature of scattering states fully suppresses Fano interference among overlapping resonances.
