We review the class of materials known as polar metals, in which polarity and metallicity
coexist in the same phase. While the notion of polar metals was first invoked more than 50 …

The nonlinear Hall effect (NLHE) reflects Berry-curvature-related properties in non-
centrosymmetric but time-reversal-symmetric materials. So far, the NLHE of the investigated …

How strong correlations and topology interplay is a topic of great current interest. In this
perspective paper, we focus on correlation-driven gapless phases. We take the time …

The symmetry breaking induced by the ferroelectric transition often triggers the emergence
of topological electronic states such as Weyl fermions in polar metals/semimetals. Such …

Electric polarization is well defined only in insulators not metals, and there is no general
scheme to induce and control bulk polarity in metals. Here we circumvent this limitation by …

We explore the thermoelectric transport properties of a coexistence topological semimetal,
characterized by the presence of both a pair of Weyl points and a nodal ring in the quantum …

Correlated-electron perovskite CaIrO 3 shows the topologically protected line node near the
Fermi level, wherein the high-mobility Dirac electrons reach the quantum limit (QL) with the …

A topological insulator is a quantum material which possesses conducting surfaces and an
insulating bulk. Despite extensive researches on the properties of Dirac surface states, the …

We explore the thermoelectric transport properties of a coexistence topological semimetal,
