The past decades have witnessed an explosion of interest in topological materials, and a lot
of mathematical concepts have been introduced in condensed matter physics. Among them …

Topological semimetals (TSMs) are characterized by bulk band crossings in their electronic
structures, which are expected to give rise to gapless electronic excitations and topological …

Bi2Te3‐based materials are not only the most important and widely used room temperature
thermoelectric (TE) materials but are also canonical examples of topological insulators in …

As spins move through a chiral electric field, the resulting spin current can acquire chirality
through a spin–orbit interaction. Such spin currents are highly useful in creating spin–orbit …

A review is given on the foundations and applications of non-Hermitian classical and
quantum physics. First, key theorems and central concepts in non-Hermitian linear algebra …

The layered vanadium antimonides AV3Sb5 (A= K, Rb, Cs) are a recently discovered family
of topological kagome metals that exhibit a range of strongly correlated electronic phases …

We study electronic instabilities of a kagome metal with a Fermi energy close to saddle
points at the hexagonal Brillouin zone face centers. Using parquet renormalization group …

Inhomogeneous superconductors can host electronic excitations, known as Andreev bound
states (ABSs), below the superconducting energy gap. With the advent of topological …

Over the past twenty-five years, mathematical concepts associated with geometric phases
have come to occupy a central place in our modern understanding of the physics of …

Spin-triplet superconductors potentially host topological excitations that are of interest for
quantum information processing. We report the discovery of spin-triplet superconductivity in …
