The topological phenomenon has been extensively studied in condensed matter physics
and has attracted much attention in many different fields. Like electrons, phonons can also …

We have given a summary on our theoretical predictions of three kinds of topological
semimetals (TSMs), namely, Dirac semimetal (DSM), Weyl semimetal (WSM) and node-line …

Topological electronic materials such as bismuth selenide, tantalum arsenide and sodium
bismuthide show unconventional linear response in the bulk, as well as anomalous gapless …

The past decade has witnessed a surge of interest in exploring emergent particles in
condensed matter systems. Novel particles, emerged as excitations around exotic band …

Thermoelectric materials transform a thermal gradient into electricity. The efficiency of this
process relies on three material-dependent parameters: the Seebeck coefficient, the …

Topological materials have been recently regarded as ideal catalysts for heterogeneous
reactions due to their surface metallic states and high carrier mobility. However, the …

We study the band topology and the associated linking structure of topological semimetals
with nodal lines carrying Z 2 monopole charges, which can be realized in three-dimensional …

In topological semimetals, the valance band and conduction band meet at zero-dimensional
nodal points or one-dimensional nodal rings, which are protected by band topology and …

A nodal loop appears when two bands, typically one electronlike and one holelike, are
crossing each other linearly along a one-dimensional manifold in reciprocal space. Here, we …

The discovery of topological quantum states marks a new chapter in both condensed matter
physics and materials sciences. By analogy to spin electronic system, topological concepts …
