Graphene is very popular because of its many fascinating properties, but its lack of an
electronic bandgap has stimulated the search for 2D materials with semiconducting …

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 …

Recent advances in atomically thin two-dimensional transition metal dichalcogenides (2D
TMDs) have led to a variety of promising technologies for nanoelectronics, photonics …

We present an open-source software package WannierTools, a tool for investigation of novel
topological materials. This code works in the tight-binding framework, which can be …

The physics of quantum materials is dictated by many-body interactions and mathematical
concepts such as symmetry and topology that have transformed our understanding of matter …

Fermions—elementary particles such as electrons—are classified as Dirac, Majorana or
Weyl. Majorana and Weyl fermions had not been observed experimentally until the recent …

Topological insulators and topological semimetals are both new classes of quantum
materials, which are characterized by surface states induced by the topology of the bulk …

Magnetic Weyl semimetals with broken time-reversal symmetry are expected to generate
strong intrinsic anomalous Hall effects, due to their large Berry curvature. Here, we report a …

Weyl semimetal is the three-dimensional analog of graphene. According to quantum field
theory, the appearance of Weyl points near the Fermi level will cause novel transport …

A ferroelectric is a material with a polar structure whose polarity can be reversed (switched)
by applying an electric field,. In metals, itinerant electrons screen electrostatic forces …
