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 …

This article reviews the recent progress in understanding the anisotropic magnetoresistance
(AMR) and the planar Hall effect (PHE) in two classes of quantum materials, the strongly …

The planar Hall effect in Weyl semimetals has been proposed as a key feature of chiral
anomaly and nontrivial Berry curvature, while the effect of fundamental spatial symmetry …

Thin crystalline layers of TaAs Weyl semimetal are grown by molecular beam epitaxy on
GaAs (001) substrates. The (001) planes of the tetragonal TaAs lattice are parallel to the …

A novel planar Hall effect (PHE) is induced by the chiral anomaly or nontrivial Berry
curvature, which has been predicted in nonmagnetic Weyl/Dirac semimetals. Recent …

Topological optics is an emerging research area in which various topological and
geometrical ideas are being proposed to design and manipulate the behaviors of photons …

In this study, we report on the planar Hall transport study of type-II Dirac semimetal PtSe 2
microflakes. The remarkable anisotropic magnetoresistance (AMR) and giant planar Hall …

We have investigated in-plane magnetotransport properties of trigonal layered PtBi 2, which
was proposed to be a triply degenerate semimetal. A remarkable planar Hall effect was …

A giant planar Hall effect with an amplitude of about 50 mΩ cm at a temperature of T= 80 K in
a magnetic field of 10 T has been detected in an ultra-pure HgSe single crystal sample with …

Multifold fermion systems feature free fermionic excitations, which have no counterparts in
high-energy physics, and exhibit several unconventional properties. Using first-principles …
