Strain Tuning the Occupation of Candidate Topological Weyl States in W‐Doped MoTe2

Advanced Science, Volume 13, Issue 50, 7 September 2026.
The present study investigates strain‐induced modifications of the electronic structure in the Weyl semimetal Td${\rm T}_d$‐Mo0.91W0.09Te2${\mathrm{Mo}}_{0.91}{\mathrm{W}}_{0.09}{\mathrm{Te}}_{2}$ using hard X‐ray angle‐resolved photoemission spectroscopy.

Near-infrared biosensors based on optical Tamm plasmons in one-dimensional photonic crystal heterostructre containing Weyl semimetals

Results in Physics
Weyl semimetals exhibit exceptional electronic and optical properties, positioning them as promising candidates for a wide range of applications. Notably, these materials naturally support surface waves in the infrared frequency range.

Terahertz transmission through TaAs single crystals in simultaneously applied magnetic and electric fields: Possible optical signatures of the chiral anomaly in a Weyl semimetal

Results in Physics, 2019
We report optical transmission measurements through a single crystal of the Weyl semimetal TaAs at terahertz frequencies. The measurements were performed at T=1.6 K using intense coherent light from a free-electron laser in high magnetic fields.

Giant Berry curvature dipole density in a ferroelectric Weyl semimetal

npj Quantum Materials, 2022
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 systems remains a tiny effect due to the lack of Weyl point as magnetic ...

2D Inorganic Electrides: Interstitial Electrons as Key Drivers of Multifunctional Properties and Applications

Advanced Science, Volume 13, Issue 50, 7 September 2026.
Eight AB‐type 2D inorganic electrides with negatively charged transition metals are theoretically designed. Their monolayers exhibit intrinsic magnetic ordering, rich topological phases, and ultralow work functions. Supported metal Ru on these 2D inorganic electrides effectively alleviates hydrogen poisoning and enables efficient ammonia synthesis ...

Axions and superfluidity in Weyl semimetals

Physical Review B
An effective field theory (EFT) for dynamical axions in Weyl semimetals (WSMs) is presented. A pseudoscalar axion excitation is predicted in WSMs at sufficiently low temperatures, independently of the strength of the Weyl fermion self-coupling. For strong fermion self-coupling the axion is the gapless Goldstone boson of chiral U(1)ch spontaneous ...

Magnetotransport Signatures of Spin–Orbit Coupling in High‐Temperature Cuprate Superconductors

Advanced Science, Volume 13, Issue 52, 18 September 2026.
Large angle‐dependent magnetoresistance and planar Hall effects emerge at the superconducting transition of YBa2Cu3O7−x$\mathrm{YBa_2Cu_3O_{7-x}}$ thin films. These anomalous transport signatures, absent in the normal state, point to spin‐polarized quasiparticle dynamics enabled by an unexpected spin–orbit coupling landscape in cuprate superconductors,

Recent advances in spin‐orbit torque and magnetization switching of transition metal oxides

InfoScience, Volume 3, Issue 3, September 2026.
This review systematically introduces recent advances in transition metal oxides spintronics, including the underlying mechanisms of spin current generation and related symmetry theory, the magnetization switching processes driven by spin currents and magnon currents, respectively, as well as their corresponding transport properties, finally presenting

Weyl geometry in Weyl semimetals

Annals of Physics
A novel oscillatory behaviour of the DC conductivity in Weyl semimetals with vacancies has recently been identified, occurring in the absence of external magnetic fields. Here, we argue that this effect has a geometric interpretation in terms of a magnetic-like field induced by an emergent Weyl connection.
