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 …

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 …

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 …

Absence of the anomalous Hall effect in planar Hall experiments

CM Wang, ZZ Du, HZ Lu, XC **e - 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 …

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 …

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 …

Intrinsic in-plane magnetononlinear Hall effect in tilted Weyl semimetals

L **ang, 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 …

Massless multifold Hopf semimetals

A Graf, F Piéchon - Physical Review B, 2023 - APS
Three-dimensional massless topological semimetals exhibit linear energy band crossing
points that act as monopoles of Berry curvature. Here, an alternative class of massless …
