Experimental perspective on three-dimensional topological semimetals

BQ Lv, T Qian, H Ding - Reviews of Modern Physics, 2021 - APS
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 …

Topological semimetals predicted from first-principles calculations

H Weng, X Dai, Z Fang - Journal of Physics: Condensed Matter, 2016 - iopscience.iop.org
We have given a summary on our theoretical predictions of three kinds of topological
semimetals (TSMs), namely, Dirac semimetal (DSM), Weyl semimetal (WSM) and node-line …

Quantized circular photogalvanic effect in Weyl semimetals

F De Juan, AG Grushin, T Morimoto… - Nature communications, 2017 - nature.com
The circular photogalvanic effect (CPGE) is the part of a photocurrent that switches
depending on the sense of circular polarization of the incident light. It has been consistently …

Light control with Weyl semimetals

C Guo, VS Asadchy, B Zhao, S Fan - Elight, 2023 - Springer
Weyl semimetals are topological materials whose electron quasiparticles obey the Weyl
equation. They possess many unusual properties that may lead to new applications. This is …

Axion-field-enabled nonreciprocal thermal radiation in Weyl semimetals

B Zhao, C Guo, CAC Garcia, P Narang, S Fan - Nano letters, 2020 - ACS Publications
Objects around us constantly emit and absorb thermal radiation. The emission and
absorption processes are governed by two fundamental radiative properties: emissivity and …

Dielectric response and novel electromagnetic modes in three-dimensional Dirac semimetal films

OV Kotov, YE Lozovik - Physical Review B, 2016 - APS
Using the Kubo formalism we have calculated the local dynamic conductivity of a bulk, ie,
three-dimensional (3D), Dirac semimetal (BDS). We obtain that at frequencies lower than …

Optical spectroscopy study of the three-dimensional Dirac semimetal

RY Chen, SJ Zhang, JA Schneeloch, C Zhang, Q Li… - Physical Review B, 2015 - APS
Three-dimensional (3D) topological Dirac materials have been under intensive study
recently. The layered compound ZrTe 5 has been suggested to be one such material as a …

Thermoelectric properties of Weyl and Dirac semimetals

R Lundgren, P Laurell, GA Fiete - Physical Review B, 2014 - APS
We study the electronic contribution to the thermal conductivity and the thermopower of Weyl
