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 …

Spin–orbit coupling (SOC) links the spin degree of freedom to the orbital motion of electrons
in a solid and plays an important role in the emergence of new physical phenomena. In non …

Spin and valley degrees of freedom in materials without inversion symmetry promise
previously unknown device functionalities, such as spin-valleytronics. Control of material …

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 possibility of reconciliation between seemingly mutually exclusive properties in one
system can not only lead to theoretical breakthroughs but also potential novel applications …

Ferroelectric Rashba semiconductors (FERSC), in which Rashba spin-splitting can be
controlled and reversed by an electric field, have recently emerged as a new class of …

Using ab initio density functional theory, we study the lattice phase transition of quasi-one-
dimensional (TaSe 4) 2 I. In the undistorted state, the strongly anisotropic semimetal band …

Weyl materials exhibiting topologically nontrivial touching points in band dispersion pave
the way to exotic transport phenomena and novel electronic devices. Here, we demonstrate …

We propose that the noncentrosymmetric LiGaGe-type hexagonal ABC crystal SrHgPb
realizes a new type of topological semimetal that hosts both Dirac and Weyl points in …

We introduce superlattices made of ferroelectric halide perovskites as a class of functional
materials possessing large Rashba effect and phase transition from normal insulator (NI) to …
