Thermoelectric Response in Nodal‐Point Semimetals

I Mandal, K Saha - Annalen der Physik, 2024 - Wiley Online Library
In this review, the thermoelectric properties in nodal‐point semimetals with two bands are
discussed. For the two‐dimensional (2D) cases, it is shown that the expressions of the …

Geometry, anomaly, topology, and transport in Weyl fermions

A Ahmad, G Varma, G Sharma - Journal of Physics: Condensed …, 2024 - iopscience.iop.org
Weyl fermions are one of the simplest objects that link ideas in geometry and topology to
high-energy physics and condensed matter physics. Although the existence of Weyl …

Absence of the anomalous Hall effect in planar Hall experiments

CM Wang, ZZ Du, HZ Lu, XC Xie - Physical Review B, 2023 - APS
Recently, the planar Hall effect has attracted tremendous interest. In particular, an in-plane
magnetization can induce an anomalous planar Hall effect with a 2 π/3 period for hexagon …

Spatial symmetry modulation of planar Hall effect in Weyl semimetals

YW Wei, J Feng, H Weng - Physical Review B, 2023 - APS
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 …

Chirality-dependent Hall effect and antisymmetric magnetoresistance in a magnetic Weyl semimetal

B Jiang, L Wang, R Bi, J Fan, J Zhao, D Yu, Z Li… - Physical Review Letters, 2021 - APS
Weyl semimetals host a variety of exotic effects that have no counterpart in conventional
materials, such as the chiral anomaly and magnetic monopole in momentum space. These …

Intrinsic in-plane magnetononlinear Hall effect in tilted Weyl semimetals

L Xiang, J Wang - Physical Review B, 2024 - APS
Armed with the extended semiclassical theory, we propose a Hall effect at EB order,
particularly in Weyl semimetals (WSMs). We dub this effect the in-plane magnetononlinear …

Decoupling intranode and internode scattering in Weyl fermions

G Sharma, S Nandy, KV Raman, S Tewari - Physical Review B, 2023 - APS
A series of recent papers claimed that intranode scattering alone can contribute to positive
longitudinal magnetoconductance (LMC) due to the chiral anomaly (CA) in Weyl semimetals …

Type-II corner modes in topolectrical circuits

SM Rafi-Ul-Islam, ZB Siu, H Sahin, MBA Jalil - Physical Review B, 2022 - APS
We study the rich properties of a topolectrical (TE) circuit array consisting of lossless basic
electrical components, such as capacitors and inductors, which can be designed to exhibit …

Tabletop Tunable Chiral Photonic Emitter

L Wang, MF Ciappina, T Brabec, X Liu - Physical Review Letters, 2024 - APS
The increasing interest in chiral light stems from its spiral trajectory along the propagation
direction, facilitating the interaction between different polarization states of light and matter …

Black hole mirages: Electron lensing and Berry curvature effects in inhomogeneously tilted Weyl semimetals

A Haller, S Hegde, C Xu, C De Beule, TL Schmidt… - SciPost Physics, 2023 - scipost.org
We study electronic transport in Weyl semimetals with spatially varying nodal tilt profiles. We
find that the flow of electrons can be guided precisely by judiciously chosen tilt profiles. In a …
