Two‐Dimensional Transition Metal Dichalcogenides Properties Enhanced by Nano‐ and Micro‐Scale Shape Control

MetalMat, Volume 3, Issue 1, March 2026.
This review explores current strategies for shaping two‐dimensional transition metal dichalcogenides (TMDs) beyond their planar form. It highlights how strain engineering, nanopatterning, and growth on complex substrates modulate their mechanical, optical, and electronic properties.

Temperature-tunable Fano resonance induced by strong coupling between Weyl fermions and phonons in TaAs

Nature Communications, 2017
The study of lattice vibrations coupled to electronic excitations may provide an avenue for exploring exotic physical phenomena. Here, Xuet al. observe a Fano resonance in the Weyl semimetal TaAs, revealing evidence for a strong coupling between phonons ...

Weyl semimetal and nonassociative Nambu geometry [PDF]

Physical Review B, 2016
Topological materials are characterized by an electronic band structure with nontrivial topological properties. In this paper, we introduce a basis of operators for the linear space of operators spanned by charge-neutral fermion bilinears. These band projected density operators are constructed using directly the eigenfunctions of the electronic energy ...

Simultaneous Broadband Nonreciprocal Thermal Emission for Transverse Magnetic and Electric Polarizations

Nanophotonics, Volume 15, Issue 6, 27 March 2026.
ABSTRACT Objects violating Kirchhoff's law of thermal radiation exhibit unequal absorptivity or emissivity at symmetrical polar angles relative to the normal direction, providing prerequisites for approaching thermodynamic limits in radiative cooling and photon energy conversion, such as the Landsberg limit.

Enhanced Weyl semimetal signature in Co3Sn2S2 Kagome ferromagnet by chlorine doping

Communications Materials
Weyl fermions are chiral massless fermions with exotic properties. In the first established magnetic Weyl semimetal, Co3Sn2S2, a giant anomalous Hall effect has been observed, while its Fermi energy remaining 60 meV from the Weyl points.

Tilted Weyl Semimetals

, 2018
Weyl semimetals, named after the physicist Hermann Weyl, were predicted theoretically about ten years ago and were found experimentally only in 2015. The topological properties of Weyl semimetals and their analogy to massless elementary particles make them a field of great interest in condensed matter physics.

Fermi Surface Structure Revealed by Quantum Oscillations in Half‐Heusler Semimetal LuAuSn

Rare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT The Fermi surface structure in the half‐Heusler semimetallic compound LuAuSn was systematically investigated using quantum oscillation studies of high‐quality single crystals and first‐principles calculations. Clear bulk quantum oscillation signals were observed for multiple complementary physical properties, including magnetization, Hall ...

Photogalvanic response in multi-Weyl semimetals

Physical Review Research
We investigate the dependence of the photogalvanic response of a twofold degenerate multi-Weyl semimetal on its topological charge, tilt, and chemical potential.
