A conventional topological insulator (TI) has gapped bulk states but gapless edge states.
The emergence of the gapless edge states is dictated by the bulk topological invariant of the …

Higher-order topological phases in crystalline and non-crystalline systems: a review Page 1

Bringing magnetic metals into superconducting states represents an important approach for
realizing unconventional superconductors and potentially even topological …

The mutual competition and synergy of magnetism and superconductivity provide us with a
very valuable opportunity to access topological superconductivity and Majorana fermions …

A d-dimensional second-order topological insulator (SOTI) can host topologically protected
(d-2)-dimensional gapless boundary modes. Here, we show that a 2D non-Hermitian SOTI …

A second-order topological insulator (SOTI) in d spatial dimensions features topologically
protected gapless states at its (d-2)-dimensional boundary at the intersection of two crystal …

Higher-order topological insulators and superconductors are topological phases that exhibit
novel boundary states on corners or hinges. Recent experimental advances in controlling …

We study the bulk-boundary correspondence for topological crystalline phases, where the
crystalline symmetry is an order-two (anti) symmetry, unitary or antiunitary. We obtain a …

We introduce two-dimensional topological insulators in proximity to high-temperature
cuprate or iron-based superconductors as high-temperature platforms of Majorana Kramers …

We investigate higher-order Weyl semimetals (HOWSMs) having bulk Weyl nodes attached
to both surface and hinge Fermi arcs. We identify a new type of Weyl node, which we dub a …
