The Anomalous Photo‐Nernst Effect of Massive Dirac Fermions In HfTe5

Advanced Physics Research
The quantum geometric Berry curvature results in an anomalous correction to the band velocity of crystal electrons with a corresponding transverse (thermo)electric conductivity.

Linear Response in Topological Materials

Applied Sciences, 2019
The discovery of topological insulators and semimetals has opened up a new perspective to understand materials. Owing to the special band structure and enlarged Berry curvature, the linear responses are strongly enhanced in topological materials.

Low‐Symmetry Weyl Semimetals: A Path to Ideal Topological States

Advanced Functional Materials, Volume 36, Issue 21, 12 March 2026.
This study presents a theoretical framework for realizing ideal Weyl semimetals, where Weyl nodes are well‐isolated at the Fermi level. The approach is exemplified in the low‐symmetry material Cu2SnSe3, which exhibits tunable topological phases, current‐induced orbital magnetization, and a strong circular photogalvanic effect, making it a promising ...

Anomalous Nernst effect in strained graphene coupled to a substrate inducing a time-reversal symmetry breaking

New Journal of Physics, 2013
A novel anomalous Nernst effect in graphene engineered by a strain and coupled to an environment with a broken time-reversal breaking is predicted. We consider the Haldane model (1988 Phys. Rev. Lett.

Combining Spin-Seebeck and Nernst Effects in Aligned MnBi/Bi Composites

Nanomaterials, 2020
The spin-Seebeck effect (SSE) is an advective transport process traditionally studied in bilayers composed of a ferromagnet (FM) and a non-magnetic metal (NM) with strong spin-orbit coupling.

Ultra‐High Spin Hall Angle in Sputtered Sb2Te3 Topological Insulators via Pt Interfacial Engineering

Advanced Physics Research, Volume 5, Issue 3, March 2026.
Topological insulator Sb2Te3 demonstrates exceptional charge‐to‐spin conversion efficiency and thermal stability up to 400°C, showing great promise for spin–orbit torque memory applications. This study achieves high‐quality Sb2Te3 films on silicon substrates through optimized sputtering and introduces an ultrathin Pt interlayer to suppress interfacial ...
